Abstract
The resurgence of mumps in vaccinated adult populations has raised concerns about possible waning vaccine immunity or a potential lack of protection to the circulating strain. A number of individual studies have investigated if there are amino acid variations between the circulating wild-type strains and vaccine strains. In these studies, the HN and F mumps surface glycoproteins have been of interest, because of their role in viral infection, and because the HN protein is the target of neutralizing antibodies. Here, we summarize the single nucleotide variants and their potential effect that have been identified between mumps genotypes in the HN and F proteins.

Characterization of mumps viruses circulating in Mongolia: identification of a novel cluster of genotype H. J Clin Microbiol 2011; 49:1917-25.

Abstract
Although mumps virus is still causing annual epidemics in Mongolia, very few epidemiological and virological data have been reported. We describe here the first phylogenetic analysis data on the mumps viruses circulated in Mongolia in 2009. We detected 21 mumps virus cDNAs and obtained a virus isolate from 32 throat swabs of mumps patients in Ulaanbaatar, the capital of Mongolia. The phylogenetic analyses based on the 316 nucleotides of the small hydrophobic gene show that these sequences form a single cluster, with the closest relatedness to the viruses belonging to genotype H. According to the recommendation of the World Health Organization, Mongolian mumps viruses could be classified into a novel genotype because the divergence between new sequences and genotype H reference viruses is >5% (6.3 to 8.2%). However, additional analyses based on the fusion gene, the hemagglutinin-neuraminidase gene, and the whole-genome indicate that the divergences between the Mongolian isolate and other genotype H strains never exceed the within-genotype divergences of other genotypes. These results suggest that Mongolia strains should be included in genotype H and that the current criteria for mumps virus genotyping should be revised. We propose here that the Mongolian viruses should be classified as a new subgenotype termed H3. Since previous epidemiological studies suggested that genotypes H may be associated with central nervous system diseases, we evaluated the neurovirulence of the Mongolian isolate in the neonatal rat system. However, the virus does not exhibit prominent neurovirulence in rats.

Abstract
The hemagglutinin (H) protein of measles virus (MV) mediates attachment to cellular receptors. The ectodomain of the H spike is thought to consist of a membrane-proximal stalk and terminal globular head, in which resides the receptor-binding activity. Like other paramyxovirus attachment proteins, MV H also plays a role in fusion promotion, which is mediated through an interaction with the viral fusion (F) protein. The stalk of the hemagglutinin-neuraminidase (HN) protein of several paramyxoviruses determines specificity for the homologous F protein. In addition, mutations in a conserved domain in the Newcastle disease virus (NDV) HN stalk result in a sharp decrease in fusion and an impaired ability to interact with NDV F in a cell surface coimmunoprecipitation (co-IP) assay. The region of MV H that determines specificity for the F protein has not been identified. Here, we have adapted the co-IP assay to detect the MV H-F complex at the surface of transfected HeLa cells. We have also identified mutations in a domain in the MV H stalk, similar to the one in the NDV HN stalk, that also drastically reduce fusion yet do not block complex formation with MV F. These results indicate that this domain in the MV H stalk is required for fusion but suggest either that mutation of it indirectly affects the H-dependent activation of F or that the MV H-F interaction is mediated by more than one domain in H. This points to an apparent difference in the way the MV and NDV glycoproteins interact to regulate fusion.

Abstract
Mumps virus (MuV), a rubulavirus of the paramyxovirus family, causes acute infections in humans. MuV has seven genes including a small hydrophobic (SH) gene, which encodes a type I membrane protein of 57 amino acid residues. The function of the SH protein is not clear, although its expression is not necessary for growth of MuV in tissue culture cells. It is speculated that MuV SH plays a role in viral pathogenesis. Simian virus 5 (SV5), a closely related rubulavirus, encodes a 44-amino-acid-residue SH protein. Recombinant SV5 lacking the SH gene (rSV5DeltaSH) is viable and has no growth defect in tissue culture cells. However, rSV5DeltaSH induces apoptosis in tissue culture cells and is attenuated in vivo. Neutralizing antibodies against tumor necrosis factor alpha (TNF-alpha) and TNF-alpha receptor 1 block rSV5DeltaSH-induced apoptosis, suggesting that SV5 SH plays an essential role in blocking the TNF-alpha-mediated apoptosis pathway. Because MuV is closely related to SV5, we hypothesize that the SH protein of MuV has a function similar to that of SV5, even though there is no sequence homology between them. To test this hypothesis and to study the function of MuV SH, we have replaced the open reading frame (ORF) of SV5 SH with the ORF of MuV SH in a SV5 genome background. The recombinant SV5 (rSV5DeltaSH+MuV-SH) was analyzed in comparison with SV5. It was found that rSV5DeltaSH+MuV-SH was viable and behaved like wild-type SV5, suggesting that MuV SH has a function similar to that of SV5 SH. Furthermore, both ectopically expressed SV5 SH and MuV SH blocked activation of NF-kappaB by TNF-alpha in a reporter gene assay, suggesting that both SH proteins can inhibit TNF-alpha signaling.

Abstract
Eleven mumps vaccine strains, all containing live attenuated virus, have been used throughout the world. Although L-Zagreb mumps vaccine has been licensed since 1972, only its partial nucleotide sequence was previously determined (accession numbers , and ). Therefore, we sequenced the entire genome of L-Zagreb vaccine strain (Institute of Immunology Inc., Zagreb, Croatia). In order to investigate the genetic stability of the vaccine, sequences of both L-Zagreb master seed and currently produced vaccine batch were determined and no difference between them was observed. A phylogenetic analysis based on SH gene sequence has shown that L-Zagreb strain does not belong to any of established mumps genotypes and that it is most similar to old, laboratory preserved European strains (1950s-1970s). L-Zagreb nucleotide and deduced protein sequences were compared with other mumps virus sequences obtained from the GenBank. Emphasis was put on functionally important protein regions and known antigenic epitopes. The extensive comparisons of nucleotide and deduced protein sequences between L-Zagreb vaccine strain and other previously determined mumps virus sequences have shown that while the functional regions of HN, V, and L proteins are well conserved among various mumps strains, there can be a substantial amino acid difference in antigenic epitopes of all proteins and in functional regions of F protein. No molecular pattern was identified that can be used as a distinction marker between virulent and attenuated strains.

Abstract
The hemagglutinin-neuraminidase (HN) protein of Newcastle disease virus mediates attachment to sialic acid receptors, as well as cleavage of the same moiety. HN also interacts with the other viral glycoprotein, the fusion (F) protein, to promote membrane fusion. The ectodomain of the HN spike consists of a stalk and a terminal globular head. The most conserved part of the stalk consists of two heptad repeats separated by a nonhelical intervening region (residues 89 to 95). Several amino acid substitutions for a completely conserved proline residue in this region not only impair fusion and the HN-F interaction but also decrease neuraminidase activity in the globular domain, suggesting that the substitutions may alter HN structure. Substitutions for L94 also interfere with fusion and the HN-F interaction but have no significant effect on any other HN function. Amino acid substitutions at other positions in the intervening region also modulate only fusion. In all cases, diminished fusion correlates with a decreased ability of the mutated HN protein to interact with F at the cell surface. These findings indicate that the intervening region is critical to the role of HN in the promotion of fusion and may be directly involved in its interaction with the homologous F protein.

Abstract
Vaccination has the potential to eradicate mumps, and 82 countries now include a live attenuated mumps vaccine as part of their childhood vaccination programme. Although, monotypic, genetic variants of mumps virus (MuV) have been described based on comparison of the SH gene sequences, and at least seven genotypes have been identified. We now report the entire sequence of a recently isolated wild type MuV strain, Glouc1/UK96 (Glouc1) by direct sequencing of the cDNA obtained from cell culture fluid. The genome of this recent isolate was 15384 nucleotides in length. There were 579 nucleotide differences (3.8%) and 71 amino acid differences (1.5%) between Glouc1, a genotype G strain and Ur-AM9, a genotype B strain. Other MuV strains with available sequences were also compared with this pathological strain. The sequence of the contemporary strain reported here provides a picture of the variability of MuV over its entire genome (GenBank accession no. AF280799).

Abstract
The aetiology of Crohn's disease remains unknown, although evidence for a viral cause has long been sought. Recent studies have shown inflammation of the submucosal microvascular endothelium and granulomata, and endothelial cell cytoplasmic inclusions, consistent with paramyxovirus, were identified by electron microscopy suggesting a persistent measles virus infection in Crohn's disease. Measles, mumps, and rubella viruses were tested for Crohn's disease by polymerase chain reaction (PCR). RNA was extracted from resected intestinal specimens from 15 patients with Crohn's disease, 14 with ulcerative colitis, and 14 controls without inflammatory bowel disease. This was used to perform nested PCR after reverse transcription (RT) of the RNA to cDNA with primer pairs directed against two regions in the genome of the measles virus and one region in the mumps and rubella viral genomes. Despite enhanced sensitivity of nested RT-PCR, measles, mumps, and rubella viral genomic sequences were not found in any intestinal specimen.

Abstract
A model is proposed for the three-dimensional structure of the paramyxovirus hemagglutinin-neuraminidase (HN) protein. The model is broadly similar to the structure of the influenza virus neuraminidase and is based on the identification of invariant amino acids among HN sequences which have counterparts in the enzyme-active center of influenza virus neuraminidase. The influenza virus enzyme-active site is constructed from strain-invariant functional and framework residues, but in this model of HN, it is primarily the functional residues, i.e., those that make direct contact with the substrate sialic acid, which have identical counterparts in neuraminidase. The framework residues of the active site are different in HN and in neuraminidase and appear to be less strictly conserved within HN sequences than within neuraminidase sequences.

Abstract
By the use of lysolecithin-permealized extracts from mumps virus-infected HeLa cells, we have developed an in vitro system, which not only directed the synthesis of mumps virus mRNAs but also supported replication of the genomic RNA. Furthermore, upon transcription of the P gene, both faithful and edited copies of the P gene were detected by RNase mapping with a riboprobe. Thus this system seems to promote biochemical analyses of underlying mechanisms operative in mumps virus gene expression and replication, including RNA editing.

Abstract
The complete nucleotide sequence of the haemagglutinin-neuraminidase (HN) gene of the porcine paramyxovirus LPMV, was determined from cDNA derived from viral genomic RNA. The gene was 1906 nucleotides long including a putative gene end and poly A signal. One long open reading frame was found encoding a protein of 576 amino acids with a calculated molecular weight of 63,324. The protein contains four potential N-glycosylation sites and a major hydrophobic region near the N-terminal, suggesting a membrane anchor domain. Comparison of the deduced amino acid sequence of the LPMV HN protein with that of other paramyxovirus HN proteins, revealed the highest amino acid identity to simian virus 5 of 43% and mumps virus of 41%.

Abstract
Sequence determinations of the hemagglutinin-neuraminidase (HN) glycoproteins of a temperature-sensitive mutant of Newcastle disease virus and two sequentially selected revertants had previously shown that substitution at a pair of residues, 129 and 175, resulted in a deficiency in neuraminidase (NA) activity, which was partially restored by a third substitution at residue 193. To evaluate the role of the substitution at residue 175 in diminished NA activity, the mutation was introduced into HN and the protein expressed in COS cells. The mutated HN not only had minimal NA activity but also was unable to absorb chicken erythrocytes, even though it was transported to the cell surface in normal amounts, in an apparently antigenic form. Attachment function was restored to the protein by the introduction of the additional substitution(s) at 129 and/or 193. These results indicate that residue 175 influences not only NA activity but also receptor recognition.

Abstract
Monoclonal antibodies (MAbs) to the hemagglutinin-neuraminidase (HN) glycoprotein of Newcastle disease virus delineate seven overlapping antigenic sites which form a continuum on the surface of the molecule. Antibodies to five of these sites neutralize viral infectivity principally by preventing attachment of the virion to cellular receptors. Through the identification of single amino acid substitutions in variants which escape neutralization by MAbs to these five antigenic sites, a neutralization map of HN was constructed, identifying several residues that contribute to the epitopes recognized by MAbs which block the attachment function of the molecule. These epitopes are defined, at least in part, by three domains on HN: residues 193 to 201; 345 to 353 (which include the only linear epitope we have identified in HN); and a C-terminal domain composed of residues 494, 513 to 521, and 569. To identify HN residues directly involved in receptor recognition, each of the variants was tested for its ability to agglutinate periodate-modified chicken erythrocytes. One variant with a single amino acid substitution at residue 193 was 2.5- to 3-fold more resistant to periodate treatment of erythrocytes than the wild-type virus, suggesting that this residue influences the binding of virus to a sialic acid-containing receptor(s) on the cell surface.

Abstract
Nonsegmented negative strand RNA viruses comprise major human and animal pathogens in nature. This class of viruses is ubiquitous and infects vertebrates, invertebrates, and plants. Our laboratory has been working on the gene expression of two prototype nonsegmented negative strand RNA viruses, vesicular stomatitis virus (a rhabdovirus) and human parainfluenza virus 3 (a paramyxovirus). An RNA-dependent RNA polymerase (L and P protein) is packaged within the virion which faithfully copies the genome RNA in vitro and in vivo; this enzyme complex, in association with the nucleocapsid protein (N), is also involved in the replication process. In this review, we have presented up-to-date information of the structure and function of the RNA polymerases of these two viruses, the mechanisms of transcription and replication, and the role of host proteins in the life-cycle of the viruses. These detailed studies have led us to a better understanding of the roles of viral and cellular proteins in the viral gene expression.

Abstract
The hemagglutinin-neuraminidase genes of the Kilham strain of mumps virus and three neutralization escape mutants (M11, M12 and M13) of this strain (Löve et al., 1985a) were sequenced using their genomes as template. The predicted amino acid sequences were compared. While one mutant had only one amino acid substitution the other two mutants had four and five respectively. A putative region for the epitope of the selected neutralizing monoclonal antibody was identified in a hydrophilic region encompassing amino acids 352-360, since the single amino acid substitution of one mutant occurred in this region and the other two mutants showed non-conserved amino acid changes in this part of the protein. The previously sequenced prototype strain RW, which lacks capacity to react with the selected neutralizing monoclonal antibody also has one non-conserved amino acid change in the region of the proposed neutralizing epitope. The three mutants showed different biological characteristics. These particular characteristics were therefore interpreted to be primarily associated with strain-specific amino acid changes outside the region of the presumed neutralizing epitope. The decrease in molecular weight in one mutant (M11) was shown to be due to a substitution in position 329 of an asparagine for an aspartic acid, leading to abolishment of a potential N-linked glycosylation site. In the other mutants, one substitution in position 239 of a lysine for a methionine was correlated with an increased neuraminidase activity of strain M12, while a substitution in position 360 of an arginine for a cysteine appeared to represent the most likely explanation for the reduced neurovirulence of strain M13.

Abstract
A guanine nucleotide insertion event has been shown to occur at a specific site within mumps virus P-gene mRNA transcripts. The region of the mRNA containing the site expected to be used for RNA editing and the complementary portion of the genomic RNA were cloned, and their nucleotide sequences were obtained. The genomic RNA was found to possess six C residues at the insertion site, whereas 63% of the P-gene-specific mRNA transcripts were found to have from two to five G residues inserted at this position in the RNA. An unedited mRNA was shown to encode the mumps virus cysteine-rich protein V, and mRNA transcripts containing two and four inserted G residues were translated to yield the mumps virus P and I proteins, respectively.

Abstract
By cDNA cloning, DNA sequencing, and RNAse mapping analyses two distinct mRNA species were shown to be transcribed from the mumps virus P gene; one faithful and the other edited copies. The former was found to direct the synthesis of the V protein (25K), while the latter, after the addition of two nontemplated G residues, was found to direct the synthesis of the P protein (40K-42K). The carboxy terminal of the V protein contained a cysteine-rich region which was similar but not identical to the metal binding domain motif found in several nucleic acid binding proteins. The V protein was detected not only in mumps virus-infected cells but also in the virions by antiserum raised against a synthetic peptide.

Abstract
The nucleotide sequence of the gene encoding the matrix (M) protein of mumps virus (MuV), Miyahara strain, has been determined from several overlapping cDNA clones. The M protein mRNA is 1248 nucleotides in length, exclusive of the poly(A) tail, and codes for a protein of 375 amino acids (Mr41,556). Comparison of the deduced amino acid sequence of the M protein of the Miyahara strain with that of the SBL-1 strain revealed that the M proteins of both strains are highly conserved. A significantly lower rate of nucleotide differences conducive to amino acid differences in the M gene compared with other genes appeared to indicate the importance of the conserved primary structure of the M protein for its function.

Abstract
The nucleotide sequence of the hemagglutinin-neuraminidase (HN) gene of human parainfluenza type 2 virus (PIV-2) was determined. The PIV-2 HN gene was 2112 nucleotides excluding poly(A) tail. There was a single large open reading frame in the mRNA which encoded a protein of 571 amino acids with a calculated molecular weight of 63,262. Analysis of the deduced amino acid sequence revealed that there were fourteen potential glycosylation sites and a major hydrophobic region near the N-terminus, which would anchor the protein in the viral membrane. Comparisons of the HN protein sequences of PIV-2 with those of Simian virus 5 (SV5), Sendai virus (SV, parainfluenza virus type 1), human parainfluenza virus type 3 (PIV-3), type 4 (PIV-4), bovine parainfluenza virus type 3 (BPIV-3), mumps virus (MuV), and Newcastle disease virus (NDV) showed definite amino acid sequence relatedness, indicating a common ancestor for these viruses. Furthermore, statistical analysis of the protein sequences suggested a possible evolutionary relatedness among the paramyxoviruses. This is the first time that a phylogenetic tree has been constructed for all the parainfluenza viruses and mumps virus which are infectious to humans. In addition, amino acid sequences involved in hemagglutinating and neuraminidase activities of paramyxovirus were discussed.

Abstract
Monoclonal antibodies (MAbs) to three overlapping antigenic sites (designated 12, 2, and 23) on the hemagglutinin-neuraminidase glycoprotein (HN) of Newcastle disease virus (NDV) were previously shown to inhibit neuraminidase activity (NA) on neuraminlactose (R. M. Iorio and M. A. Bratt, 1984a, J. Immunol. 133, 2215-2219; R. M. Iorio et al., 1989, Virus Res. 13, 245-262). However, a competitive inhibitor of NA blocks the binding of only MAbs to site 23, suggesting that the domain they recognize may be closely related to the NA site. Antigenic variants selected with site 23 MAbs have single amino acid substitutions at HN residues 192, 193, or 200. Virions of variants, which have a substitution at residue 193 or 200, have alterations in NA which are not attributable to a commensurate change in HN content. A revertant of a temperature-sensitive mutant, which has markedly diminished NA relative to the wild type, has an amino acid substitution at residue 175. A second step revertant having partially restored NA has an additional substitution at residue 192 identical to that in one of the site 23 variants, which, in turn, also makes the revertant resistant to neutralization by site 23 MAbs. Thus, an amino acid substitution at residue 175, 193, or 200 of the HN of NDV can have marked effects on the NA of the protein. The amino acids in the region around residue 175 are highly conserved between the HNs of NDV and other paramyxoviruses, suggesting that this domain is important to the integrity of the NA site in this group of viruses.

Abstract
cDNA clones representing the M, F and a putative SH gene of the SBL strain of mumps virus have been prepared and their nucleotide sequence determined. The M gene of mumps virus appears to contain 1253 nucleotides and codes for a protein of 375 amino acid residues (Mr 41,589). The protein is hydrophobic and the deduced amino acid sequence shows homologies with those of other paramyxoviruses. The F gene of the SBL strain was compared to that of the RW strain [Waxham et al. (1987) Virology 159, 381-388]. The F gene is 1727 nucleotides long and codes for a protein of 538 amino acids (Mr 58,789). There are substantial variations between the F gene sequences of various mumps virus strains. The F gene is followed by a small (315 nt) transcription unit which contains an open reading frame of 57 amino acids encoding a very hydrophobic protein (Mr 6712). This may be similar to the SH gene of SV5, although there appears to be no sequence homology between the SV5 SH protein and the putative SH protein of mumps virus. A physical and transcription map of mumps virus indicates the gene order to be 3'-N-P-M-F-SH-HN, similar to that of other paramyxoviruses and SV5 in particular.

Abstract
The complete nucleotide sequence of the hemagglutinin-neuraminidase protein (HN) mRNA of the virulent SBL-1 strain of mumps virus has been determined. The mRNA contains 1887 nucleotides excluding the poly(A). The protein encoded by the mRNA has 582 amino acids and a membrane anchorage domain near the amino terminus. The calculated molecular mass (64 kDa) of the protein is in good agreement with that of the unglycosylated HN protein (63 kDa) identified in tunicamycin treated mumps virus infected cells (Herrler and Compans, 1983). The predicted sequence has nine potential N-glycosylation sites out of which two contain a cysteine residue and one has a proline residue as the variable amino acid X in the glycosylation site (Asn-X-Ser or Asn-X-Thr) and therefore, may not be utilized. One potential glycosylation site is in the cytoplasmic region which may not also be glycosylated. Comparison of the mumps HN protein sequence with the HN protein sequences of Sendai virus, simian-virus 5 (SV5), parainfluenza virus type 3 and Newcastle disease virus (NDV) shows two major homology regions, one region near the middle of the protein and the other in the second half of the molecule. In terms of percentage amino acid homology, the HN proteins of mumps virus, SV5 and NDV are closely related to each other but distinct from Sendai virus and parainfluenza virus type 3 HN proteins.

Abstract
We previously described sialidase-deficient variants of the O'Take strain of mumps virus obtained by growth under the selective pressure of the competitive sialidase inhibitor 2-deoxy-2,3-dehydro-N-acetylneuraminic acid (DANA). In this report, we describe the production of a sialidase-deficient variant of the RW strain of mumps virus using an identical selection protocol. The biologic activities of the RW variant, RW(DANA)v1, were identical to those described for O'Take-(DANA)v1 and included a lack of detectable sialidase activity, unchanged hemagglutination activity, and expression of cell-to-cell fusion in infected cell monolayers. Analysis of the structural proteins of each virus by both two-dimensional tryptic peptide mapping and monoclonal antibody binding assays suggested that limited changes occurred in the hemagglutinin-neuraminidase (HN) proteins and that only the HN proteins were altered. The complete nucleotide sequence of the RW(DANA)v1 HN was determined and compared to the HN sequence of the RW parent. Two nucleotide differences accounting for two nonconservative amino acid differences were noted; an lle to a Thr at amino acid 181 and a Gln to Lys at amino acid 261 from RW to RW(DANA)v1, respectively. By comparing the data presented here with those reported for several other paramyxoviruses, we tentatively identify amino acid 181 as a critical residue in the active site of the mumps virus sialidase enzyme.
