Abstract
The Drosophila Notch gene has been shown to be involved in the determination of fate in a number of different cell types. Similarly, Notch homologues in Caenorhabditis elegans are involved in cell decision-making steps. It is of interest to determine if a mammalian Notch homologue plays a role in cell fate determination. We have isolated cDNA from a mouse Notch gene using low-stringency hybridization with probes derived from the Xenopus Notch gene. Sequence analysis reveals that this gene possesses EGF repeats, Notch/lin-12 repeats, and CDC-10/SWI-6 repeats, characteristic of other Notch homologues. Northern analysis revealed that the transcript size was roughly 10 kb as has been found for the other Notch genes. We have studied the expression pattern of the gene by both conventional and whole mount in situ hybridization. Expression patterns were consistent with mouse Notch having a determinative role in the formation of mesoderm, somites, and the nervous system.

Abstract
Recently, a novel subgroup of nuclear hormone receptors called RXRs implicated for retinoid-mediated gene regulation have been identified. RXRs appear to interact with many other nuclear hormone receptors and modulate their functions. We have mapped genetic loci Rxra, Rxrb, and Rxrg encoding three RXR subtypes, RXR alpha, RXR beta, and RXR gamma, respectively, using interspecific backcross mice. None of the Rxr loci cosegregated with each other or with the retinoic acid receptor loci (Rar) mapped previously. Rxra mapped to Chr 2 near the centromere, Rxrb mapped to the H-2 region of Chr 17, and Rxrg was tightly linked to the Pbx gene on distal Chr 1. These results underscore that RXR genes are dispersed in the genome.

Abstract
Comparative mapping studies in human and mouse have shown that, to date, human Chromosome (Chr) 20 is completely syntenic with distal mouse Chr 2. The structural locus for S-adenosyl-L-homocysteine hydrolase (EC 3.3.1.1) in human, AHCY, maps to 20 qter-->q13.1, and we report here that the homologous locus in the mouse, Ahcy, maps to distal mouse Chr 2 with gene order Pcna-Ahcy-Ada. Analysis of 123 progeny of an interspecific backcross between a laboratory stock, AN, and Mus spretus using a rat cDNA probe revealed the presence of at least two other Ahcy-related sequences segregating independently in the mouse genome. One, Ahcy-rs1, was mapped to Chr 8 in the BXH recombinant inbred strains, and the other, Ahcy-rs2, shows a pattern of inheritance consistent with X-linkage.

Abstract
We have extended our pulsed-field gel map of the region of the mouse X chromosome homologous to human Xq28 to include the loci Gdx (DXS254Eh), P3 (DXS253Eh), G6pd, Cf-8, and F8a. Gdx, P3, and G6pd are demonstrated to be physically linked to the X-linked visual pigment locus (Rsvp) within a maximal distance of 340 kb, while G6pd and Cf-8 are approximately 900 kb apart. These studies favor a gene order of cen-Rsvp-Gdx-P3-G6pd-(Cf-8)-tel and extend the physical map of this region to 5 million bp. In conjunction with previous physical mapping studies in both mouse and human, the results suggest conserved linkage for loci in this region of the mouse X chromosome and human Xq28. However, employing pulsed-field gel electrophoresis and genetic pedigree analysis of interspecific backcross progeny, we have found close linkage of a clone encoding a mouse homolog for human factor VIII-associated gene A (F8A) to DXPas8, thus revealing the first exception to conserved gene order between murine and human loci in the region.

Abstract
The inter-alpha-inhibitor (I alpha I) and pre-alpha-inhibitor (P alpha I) family is composed of three plasma protease inhibitors, I alpha I, P alpha I, and bikunin, whose chains are encoded by a set of three evolutionarily related heavy (H) chain genes designated H1, H2, and H3 and a fourth gene, the so-called alpha 1-microglobulin/bikunin precursor (AMBP) gene. The latter codes for a precursor that splits into: (i) alpha 1-microglobulin, which belongs to the lipocalin superfamily; and (ii) bikunin, which is made up of two tandemly arranged protease inhibitor domains and belongs to the superfamily of Kunitz-type protease inhibitors. The bikunin chain is found in I alpha I and P alpha I molecules and it is also present as a free molecule in plasma. In human, the AMBP and H2 genes have been mapped to 9q32-q34 and 10p14-p15, respectively, while the H1 and H3 genes are tandemly located at 3p21.1-p21.2. In situ hybridization mappings indicate that the mouse AMBP gene (Intin-4) is located at 4C1----C4, and the H1 (Intin-1) and H3 (Intin-3) genes are colocated at 14A2----C1. In interspecific backcrosses (C57BL/6Pas x Mus spretus) a TaqI restriction variant in (and/or near) the H2 (Intin-2) gene identified a linkage of this gene with other polymorphic loci, which assigns Intin-2 to the centromeric area of chromosome 2. All such assignments are in conserved chromosomal regions between human and mouse. Therefore the genetic events that gave rise to the four I alpha I family genes took place prior to the divergence between human and mouse.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Dlx-2 (also called Tes-1), a mammalian member of the Distal-less family of homeobox genes, is expressed during murine fetal development in spatially restricted domains of the forebrain. Searching for a candidate neurological mutation that might involve this gene, we have assigned the human and mouse loci to regions of conserved synteny on human chromosome 2, region cen--q33, and mouse chromosome 2 by Southern analysis of somatic cell hybrid lines. An EcoRI dimorphism, discovered in common inbred laboratory strains, was used for recombinant inbred strain mapping. The results place Dlx-2/Tes-1 near the Hox-4 cluster on mouse chromosome 2.

Abstract
The mapping of human chromosome 9 (HSA9) and mouse chromosome 2 (MMU2) has revealed a conserved syntenic region between the distal end of the long arm of chromosome 9 and proximal mouse chromosome 2. Two genes that map to human chromosome 9q34, gelsolin (GSN) and dopamine beta-hydroxylase (DBH), have not previously been located in the mouse. We have used an interspecific backcross to map each of these genes, by Southern blot analysis, to mouse chromosome 2. Gelsolin (Gsn) is tightly linked to the gene for complement component C5 (Hc), and dopamine beta-hydroxylase (Dbh) is just proximal to the Abelson leukemia virus oncogene (Abl) and alpha-spectrin 2 (Spna-2). The loci for gelsolin and dopamine beta-hydroxylase therefore form part of the conserved synteny between HSA9q and MMU2.

Abstract
The structural gene for proliferating cell nuclear antigen (Pcna) has been mapped to mouse Chromosome (Chr) 2 by use of a PCR-based assay. With somatic cell hybrids, Pcna was mapped between the T(2;4)13H and T(2;4)1Sn breakpoints. An interspecific backcross was employed to map Pcna 1.9 +/- 1.3 cM distal to Il-lb. This was confirmed by mapping Pcna in the BXH recombinant inbred (RI) strains; no recombinants were seen between Il-la and Pcna. In addition, a PCNA-related sequence (Pcna-rsl) was mapped to Chr 19 in the BXH RI strains.

Abstract
The genes for orosomucoid (ORM-1 and ORM-2), delta-aminolevulinate dehydratase (ALAD), and hexabrachion or tenascin (HXB) all map to the q31-qter region of human Chromosome (Chr) 9. The mouse homolog of each of these genes has been mapped to Chr4, but hexabrachion has not previously been mapped by linkage analysis. We have now ordered Orm-1, Lv (the mouse homolog of ALAD), and Hxb in an interspecific backcross panel, by use of tyrosinase related protein-1, Tyrp-1, whose human homolog maps to 9p13-pter (Abbott et al., Genomics 1991) as a reference locus. No recombinants were identified in 124 animals between Lv and Orm-1. Hxb was found to be 1.6 cM distal to Lv and Orm-1, and 4.8 cM proximal to Tyrp-1, or b. These data therefore contribute to our knowledge of the conserved synteny between HSA 9q and MMU 4.
