Somatic cell mapping of bovine clathrin light chain genes: identification of a new bovine synthenic group

摘要

Two bovine DNA probes (LCa and LCb) complementary to the clathrin light chain genes were hybridized to DNAs from bovine hamster hybrid somatic cell lines retaining different combinations of bovine chromosomes. Concordancy of retention of the clathrin genes was compared to existing syntenic data for the domestic cow. LCb, identified a single locus, CLTB, concordant with the genes encoding bovine anti-Müllerian hormone (AMH) and bovine osteonectin from bovine syntenic group U22. LCa recognized two loci, CLTAL1 from a previously unidentified bovine syntenic group, U25, and CLTAL2 which is concordant with GGTB2, a gene marker for bovine syntenic group U18
