Abstract
In order to isolate genes that may not be represented in current human brain cDNA libraries, we have sequenced about 20,000 sequence tags of cDNA clones derived from cerebellum and parietal lobe of cynomolgus monkeys (Macaca fascicularis). We determined the entire cDNA sequence of approximately 700 clones whose 5'-terminal sequences showed no homology to annotated putative genes or expressed sequence tags in current databases of genetic information. From this, 118 clones with sequences encoding novel open reading frames of more than 100 amino acid residues were selected for further analysis. To localize the genes corresponding to these 118 newly identified cDNA clones on human chromosomes, we performed a homology search using the human genome sequence and fluorescent in situ hybridization. In total, 108 of 118 clones were successfully assigned to specific regions of human chromosomes. This result demonstrates that genes expressed in cynomolgus monkey are highly conserved throughout primate evolution, and that virtually all had human homologs. Furthermore, we will be able to discover novel human genes in the human genome using monkey homologs as probes.

Abstract
Casein kinase 1 gamma1(CK1 gamma1) is known to be involved in the growth and morphogenesis of eukaryotic cells. We have isolated two types of cDNA for human casein kinase 1 gamma1 (hCK1 gamma1). One of them (hCK1 gamma1S) was found to encode a polypeptide consisting of 393 amino acids, which is highly homologous with already reported rat CK1 gamma1 (rCK1 gamma1). The other type of cDNA (hCK1 gamma1L) encodes a polypeptide consisting of 422 amino acids, which is quite identical in the kinase domain, but different in the C-terminal sequence from hCK1 gamma1S. Namely, hCK1 gamma1L has a characteristic sequence of 50 amino acids at the C-terminal end and this motif was shown to be shared by the casein kinase gamma2 and gamma3 from rat and human, suggesting that it is a signature sequence of the gamma-isoforms. In this sense, newly isolated hCK1 gamma1L might be the original form of CK1 gamma1 subspecies rather than rCK1 gamma1 and hCK1 gamma1S. RT-PCR analysis revealed that hCK1 gamma1S mRNA is predominantly present in the testis, whereas the abundance of hCK1 gamma1L mRNA was nearly the same in the twelve tissues examined. These results suggest that novel hCK1 gamma1L may have a unique functional role different from that of hCK1 gamma1S and rCK1 gamma1. The human hCK1 gamma1 gene (CSNK1G1) was mapped to chromosome 15q22.1-->q22.31 by fluorescence in situ hybridization.

Abstract
The intron-containing genes encoding human and mouse ribosomal protein (r-protein) L27A were cloned and sequenced. The human r-protein L27A gene (RPL27A) shared an identical exon/intron structure with the mouse r-protein 27A gene (Rpl27a). The translational start codon ATG was separated from the main reading frame by the first intron sequence in both genes. An approximately 200-bp sequence upstream of the translational start site of both genes displayed remarkable similarity, and contained the putative promoters lacking canonical TATA, but harbored Sp1 binding sites and a short stretch of pyrimidine cluster, similar to other r-protein genes. Transcriptional regulatory elements, Box-A and GABP, found in the promoters of some other r-protein genes were also conserved in both genes. These structural features were included in the typical CpG island identified in the 5'-end sequences, suggesting that RPL27A/Rpl27a cloned here are authentic and transcriptionally active. Fluorescence in situ hybridization (FISH) analysis localized the mouse intron-containing Rpl27a to chromosome 7E2-F1 syntenic to human chromosome 11p15, where human RPL27A was located.

Abstract
A sequence homologous to the transaldolase gene (TALDO) was identified in a polymorphic cosmid DNA mapped on human chromosome 11p15 by exon trapping with pSPL3. Analysis of lambda clones contiguous to the cosmid clone showed that the related gene (TALDOR) consists of 8 exons spanning approximately 19kb from the translation start site to the polyadenylation signal. The exon sequence of TALDOR was almost identical with that of TALDO localized on 1p33-34. 1, but its exons corresponding to exons 4 and 5 of TALDO were found to be split by 4 introns in TALDOR. To examine the evolutionary conservation of two genes for transaldolase, we have isolated the cDNA for its mouse homolog and determined the nucleotide sequence covering the complete coding region. Fluorescence in situ hybridization using the cDNA as a probe showed that the mouse transaldolase gene (Taldo) is localized on chromosome 7 F3-F4 as a single copy gene. This chromosomal region is known to be syntenic to human chromosome 11p15 rather than to 1p33-p34.1, suggesting that TALDOR is the ancestral form. The existence of TALDOR implies a duplication of the mammalian transaldolase gene after divergence of rodent and primate.

Abstract
In order to determine the chromosomal locations of an autoimmune antigen, the coilin gene and its pseudogene, we amplified the segments of the two genes by the polymerase chain reaction (PCR) and screened a panel of somatic cell hybrids for the presence of the gene products. The results indicate that the human coilin gene and its pseudogene can be assigned to chromosome 17 and chromosome 14, respectively. Further analysis of cell hybrids bearing chromosome 17 with various deletions localized the coilin gene to the region q21-q23.
