Four genes having homologous loci on the short arm of human chromosome 8 have been mapped to two different bovine syntenic groups. The gene coding for the tissue-type plasminogen activator mapped with GSR, a human chromosome 8 marker, of syntenic group U14 while lipoprotein lipase and the medium and light neurofilament polypeptide genes were shown to be syntenic with the human chromosome 9 marker GGTB2 of syntenic group U18.

Sheep x hamster cell hybrids containing sheep metacentric Chromosome (Chr) 2 were produced by fusing blood leukocytes from normal sheep with hamster auxotrophic Ade F-minus mutants. Cell clones that were isocitrate dehydrogenase 1 (IDH1) positive were cytogenetically characterized, confirming that they contained sheep Chr 2. The following loci were newly assigned by Southern hybridization to sheep Chr 2: lipoprotein lipase (LPL), glycoprotein-4-beta galactosyltransferase 2 (GGTB2), neurofilament light polypeptide (68 kDa; NEFL), surfactant-associated protein 2 (SFTP2), lymphocyte-specific protein tyrosine kinase (LCK), and nebulin (NEB). These new assignments and the in situ localization of gelsolin (GSN) to sheep Chr 2pter-p24 are consistent with the predicted homology of cattle Chr 8 (U18) with sheep Chr 2p, and of cattle Chr 2 (U17) with sheep 2q. In addition, the assignment by cell hybrid analysis of loci previously mapped to Chr 2 in sheep, viz., cholinergic receptor, nicotinic, delta polypeptide (CHRND), collagen type III alpha 1 (COL3A1), fibronectin 1 (FN1), isocitrate dehydrogenase (IDH1), and villin 1 (VIL1), confirmed the localization of sheep syntenic group U11 to this chromosome. By nutritional selection and complementation of the hamster auxotrophic Ade F mutation, the multifunctional enzyme locus phosphoribosylaminoimidazolecarboxamide formyltransferase (AICAR transformylase)/IMP cyclohydrolase (inosinicase) (provisionally given the symbol PRACFT) has also been newly assigned to sheep Chr 2. This report significantly extends the number of loci physically mapped to sheep Chr 2 and confirms its close homology with cattle Chrs 2 and 8.

Bone morphogenetic protein 1 (BMP1) has been proposed as a regulatory molecule involved in the binding or activation of other BMP molecules. It has been described as being identical to the enzyme C-proteinase that processes procollagens to fibrillar collagens. A fragment containing an exon of the bovine BMP1 gene was amplified from an adapter-ligated genomic DNA library. The isolated bovine BMP1 fragment was assigned by fluorescence in situ hybridization (FISH) to bovine (BTA) chromosome 8q21, a region containing an evolutionary breakpoint between homology to human (HSA) chromosomes 8 and 9. The assignment to BTA 8 was confirmed by using a hybrid somatic cell panel. The 3' intron region of the amplified genomic BMP1 fragment showed a SSCP polymorphism, and linkage analysis in the International Bovine Reference Panel (IBRP) of families confirmed the boundary position of this gene. The BMP1 gene presents total linkage (theta = 0.00, Z = 3.61) with the lipoprotein lipase gene on BTA 8 and HSA 8 and a larger recombination fraction (theta = 0.11, Z = 5.03) with the marker GGTB2 on BTA 8 and HSA 9. Physical and genetic mapping of the bovine BMP1 gene contribute to narrow the boundary between the HSA 8 and HSA 9 homology segments on BTA 8 and to the comparative mapping between BTA 8, murine chromosome MMU 14, and HSA 8.
