Three mouse chromosomes (MMU 1, 3, and 4) carry homologs of human chromosome 1 (HSA 1) genes. A similar situation is found in the bovine, where five bovine chromosomes (BTA 2, 3, 5, 16, and unassigned syntenic group U25) contain homologs of HSA 1 loci. To evaluate further the syntenic relationship of HSA 1 homologs in cattle, 10 loci have been physically mapped through segregation analysis in bovine-rodent hybrid somatic cells. These loci, chosen for their location on HSA 1, are antithrombin 3 (AT3), renin (REN), complement component receptor 2 (CR2), phosphofructokinase muscle type (PFKM), Gardner-Rasheed feline sarcoma viral (v-fgr) oncogene homolog (FGR), alpha fucosidase (FUCA1), G-protein beta 1 subunit (GNB1), alpha 1A amylase, (AMY1), the neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS), and alpha skeletal actin (ACTA1). AT3, REN, CR2, and GNB1 mapped to BTA 16, PFKM to BTA 5, AMY1A and NRAS to BTA 3, FGR and FUCA1 to BTA 2, and ACTA1 to BTA 28.

Human salivary and pancreatic alpha-amylases (HSA and HPA) are the respective gene products of the AMY1 and AMY2A genes. AMY2B is a newly found human alpha-amylase gene. The presence of the AMY2B gene product (HXA) in the urine of healthy humans was examined. A mixture of alpha-amylases that seemed to contain HXA, judging from the substrate specificity, was purified from urine of healthy volunteers by affinity adsorption on starch and then by ion-exchange chromatography. The mixture was reduced and S-alkylated, and the product was digested with trypsin. The digest was separated by reversed-phase HPLC. LVGLLDLALEKDYVR and LVGLLDLALEK, which were found in the digest, are peptides of HXA, but not of HSA and HPA. The detection of these characteristic peptides of HXA demonstrates the presence of HXA in the urine of healthy humans.
