Abstract
The mammalian genome contains hundreds if not thousands of zinc finger protein (Zfp) genes. While the function of most of these genes remains to be determined, it is clear that a few of them play important roles in gene regulation and development. In studies described here, we have used an interspecific mouse backcross mapping panel to determine the chromosomal location of 15 KRAB-containing zinc finger loci. These loci map to nine different mouse autosomes and the X Chromosome (Chr). Two Chrs, 7 and 9, contain cosegregating pairs of KRAB-containing Zfp genes, indicating that the KRAB-containing Zfp genes have evolved through processes involving regional as well as genome-wide duplication events.

Abstract
To enhance the comparative map for human Chromosome (Chr) 13, we identified clones for human genes and anonymous loci that cross-hybridized with their mouse homologs and then used linkage crosses for mapping. Of the clones for four genes and twelve anonymous loci tested, cross-hybridization was found for six, COL4A1, COL4A2, D13S26, D13S35, F10, and PCCA. Strong evidence for homology was found for COL4A1, COL4A2, D13S26, D13S35, and F10, but only circumstantial homology evidence was obtained for PCCA. To genetically map these mouse homologs (Cf10, Col4a1, Col4a2, D14H13S26, D8H13S35, and Pcca-rs), we used interspecific and intersubspecific mapping panels. D14H13S26 and Pcca-rs were located on the distal portion of mouse Chr 14 extending by approximately 30 cM the conserved linkage between human Chr 13 and mouse Chr 14, assuming that Pcca-rs is the mouse homolog of PCCA. By contrast, Cf10, Col4a1, Col4a2, and D8H13S35 mapped near the centromere of mouse Chr 8, defining a new conserved linkage. Finally, we identified either a closely linked sequence related to Col4a2, or a recombination hot-spot between Col4a1 and Col4a2 that has been conserved in humans and mice.

Abstract
The nude mutation produces the apparently disparate phenotypes of hairlessness and congenital thymic aplasia. These pleiotropic defects are the result of a single, autosomal recessive mutation that was previously mapped to a 9-cM region of murine chromosome 11 bounded by loci encoding the acetylcholine receptor beta subunit and myeloperoxidase. In this study, exclusion mapping of a panel of congenic nude strains was used to place the nude locus between the microsatellite loci D11Nds1 and D11Mit8. The relative distance from nude to each of these loci was determined by analyzing a large segregating cross. Thus, nude lies 1.4 cM distal to D11Nds1 and is 0.5 cM proximal to D11Mit8. Mice that carried recombinational breakpoints between D11Nds1 and D11Mit8 were further analyzed at the loci Evi-2 and D11Mit34, which placed nu 0.2 cM proximal to these markers. D11Nds1 and Evi-2/D11Mit34 thus define the new proximal and distal boundaries, respectively, for the nu interval. We also report the typing of the above microsatellite markers in the AKXD, AKXL, BXD, CXB, and BXH recombinant inbred strains, which confirmed the relative order and separation of loci in this region.

Abstract
Insulin-like growth factor-binding protein-1s are important modulators of the insulin-like growth factors that may have both positive and negative effects on the ability of insulin-like growth factors to stimulate cell growth. The IGFBP-1 gene is one of the most highly induced immediate-early genes after partial hepatectomy. The IGFBP-1 gene is also expressed at a high level during fetal liver development and in response to nutritional changes and diabetes. Therefore it may have important roles in liver growth and metabolism. To begin to examine the regulation of this gene, we cloned and sequenced the entire mouse IGFBP-1 gene. Its structure is highly similar to that of the human gene, and, in addition to the exonic regions, the two genes are highly conserved in specific regions in the promoter and first intron. Analysis of this conservation allows us to predict important regulatory sites that define the tissue specific and insulin-mediated regulation of the gene and identify potential sites that might be important for the transcriptional induction during liver regeneration. The mouse gene is located on mouse chromosome 11; it is found at the boundary between regions in the mouse genome homologous to human chromosomes 22 and 7. We found IGFBP-1 mRNA in both parenchymal and nonparenchymal RNA after partial hepatectomy. Using in situ hybridization of IGFBP-1 mRNA in regenerating rat liver tissue, we demonstrated IGFBP-1 transcripts in several cell types. We found that IGFBP-1 gene induction after partial hepatectomy is paralleled by protein expression.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We have isolated two mouse genes, Mox-1 and Mox-2 that, by sequence, genomic structure and expression pattern, define a novel homeobox gene family probably involved in mesodermal regionalization and somitic differentiation. Mox-1 is genetically linked to the keratin and Hox-2 genes of chromosome 11, while Mox-2 maps to chromosome 12. At primitive streak stages (approximately 7.0 days post coitum), Mox-1 is expressed in mesoderm lying posterior of the future primordial head and heart. It is not expressed in neural tissue, ectoderm, or endoderm. Mox-1 expression may therefore define an extensive ‘posterior’ domain of embryonic mesoderm before, or at the earliest stages of, patterning of the mesoderm and neuroectoderm by the Hox cluster genes. Between 7.5 and 9.5 days post coitum, Mox-1 is expressed in presomitic mesoderm, epithelial and differentiating somites (dermatome, myotome and sclerotome) and in lateral plate mesoderm. In the body of midgestation embryos, Mox-1 signal is restricted to loose undifferentiated mesenchyme. Mox-1 signal is also prominent over the mesenchyme of the heart cushions and truncus arteriosus, which arises from epithelial-mesenchymal transformation and over a limited number of craniofacial foci of neural crest-derived mesenchyme that are associated with muscle attachment sites. The expression profile of Mox-2 is similar to, but different from, that of Mox-1. For example, Mox-2 is apparently not expressed before somites form, is then expressed over the entire epithelial somite, but during somitic differentiation, Mox-2 signal rapidly becomes restricted to sclerotomal derivatives. The expression patterns of these genes suggest regulatory roles for Mox-1 and Mox-2 in the initial anterior-posterior regionalization of vertebrate embryonic mesoderm and, in addition, in somite specification and differentiation.

Abstract
Ninety-three phage clones identified by hybridization with a C2-H2 zinc finger sequence probe have been grouped into 23 genetic loci. Partial sequencing verified that each locus belonged to the zinc finger family. Oligonucleotide primer pairs were developed from these sequences to serve as STS markers for these loci. One or more clones from each locus was mapped onto human metaphase chromosomes by fluorescence in situ hybridization. Several loci map to identical chromosomal regions, indicating the possible presence of multigene clusters. Zinc finger loci were found to reside predominantly either in telomeric regions or in chromosomal bands known to exhibit chromosome fragility. Chromosome 19 carries a disproportionate fraction (10 of 23) of the mapped zinc finger loci.

Abstract
Retinoic acid is essential for normal development and growth of structures such as head and limbs, and it can act as morphogen or teratogen. Retinoic acid induces expression of genes such as the homeobox genes and keratin type I and type II genes. Retinoic acid receptors are nuclear transcription factors that play a key role in retinoid physiology. As part of the characterization of retinoic acid receptor gene family, linkage of genes encoding the three receptors was determined by using interspecific backcross and recombinant inbred strain analysis of restriction fragment variants. Retinoic acid receptor alpha is located on mouse Chromosome (Chr) 11 near the homeobox-2 complex and the keratin type I gene complex, whereas retinoic acid receptor gamma is on mouse Chr 15 near the homeobox-3 complex and the keratin type II complex. Close genetic proximity of these functionally related genes may be significant. We confirmed assignment of retinoic acid receptor beta to the centromeric portion of Chr 14. These linkage assignments provide further evidence for duplicated segments in the mouse genome.

Abstract
Recent evidence suggests that the human neuromuscular disorders, hyperkalemic periodic paralysis and paramyotonia congenita, are both caused by genetic defects in the alpha-subunit of the adult skeletal muscle sodium channel, which maps near the growth hormone cluster (GH) on Chromosome (Chr) 17q. In view of the extensive homology between this human chromosome and mouse Chr 11, we typed an interspecies backcross to determine whether the murine homolog (Scn4a) of this sodium channel gene mapped within the conserved chromosomal segment. The cytosolic thymidine kinase gene, Tk-1, was also positioned on the genetic map of Chr 11. Both Scn4a and Tk-1 showed clear linkage to mouse Chr 11 loci previously typed in this backcross, yielding the map order: TrJ-(Re, Hox-2, Krt-1)-Scn4a-Tk-1. No mouse mutant that could be considered a model of either hyperkalemic periodic paralysis or paramyotonia congenita has been mapped to the appropriate region of mouse Chr 11. These data incorporate an additional locus into the already considerable degree of homology observed for these human and mouse chromosomes. These data are also consistent with the view that the conserved segment region may extend to the telomere on mouse Chr 11 and on human 17q.

Abstract
alpha-L-iduronidase (IDUA), which when deficient causes mucopolysaccharidosis type I, is located near the Huntington disease locus (HD) on human Chromosome (Chr) 4p16.3, approximately 10(6) base pairs (bp) from the telomere. As part of our continuing efforts to define a detailed comparative map for this chromosomal segment in mice and humans, we have used an interspecific backcross between C57BL/6J and an inbred strain derived from Mus spretus to map Idua, the mouse homolog of IDUA. We also mapped the mouse homolog of D4S115, an anonymous locus approximately 250 kb proximal to IDUA. As expected, both Idua and D4S115h are located on the proximal portion of mouse Chr 5 near homologs for other loci on human Chr 4p. Comparison of gene order in mice and humans demonstrates, however, that a chromosomal rearrangement within this conserved synteny has occurred since divergence of lineages leading to mice and humans.

Abstract
A cDNA was isolated from a T cell library using an oligonucleotide probe corresponding to a sequence conserved in proteins with multiple zinc fingers of the C2H2 type. The predicted protein structure of this cDNA (ZNF43) showed that it contained 22 of the Krüppel type of zinc finger motifs in tandem. The amino acid sequence was strongly conserved between each of the finger domains of this cDNA, except for variable residue positions within the putative DNA binding site. Within the zinc finger domain the amino acid sequence of the four zinc fingers 6 to 9 was very similar to the amino acid sequence of fingers 10 to 13, the DNA sequence bound by this group of eight fingers may include a short repeat. Southern blotting showed that ZNF43 was one of a closely related family of proteins with 10 to 20 members. The members of the ZNF43 family did not appear to be clustered at the chromosomal level. The transcription of many members of this gene family was increased in lymphoid cell lines. After in vitro induced terminal differentiation of the human HL60 cell line the expression of the ZNF43 family was reduced. The expression of the ZNF43 gene was mainly limited to T and B cell lines. The gene was differentially spliced and different cell lines expressed different combinations of transcripts.

Abstract
Two members of the zinc finger Krüppel family, ZNF24 (KOX17) and ZNF29 (KOX26), have been localized by somatic cell hybrid analysis and in situ chromosomal hybridization to human chromosomes 18q12 and 17p13-p12, respectively. The mapping of ZNF29 together with the previously reported localization of ZFP3 suggests that a zinc finger gene complex is located on human chromosome 17p. ZNF29 maps centromeric to the human p53 tumor antigen gene (TP53). In the analogous murine position, the two mouse zinc finger genes Zfp2 and Zfp3 have recently been assigned to the distal region of mouse chromosome 11, the murine homolog of human chromosome 17. Both human zinc finger genes ZNF24 and ZNF29 are in chromosomal regions that have been noted to be deleted in neoplasms of the lung and of the central nervous system at chromosome 17p and in colorectal neoplasia at chromosomes 17p and 18q.
