Comparative FISH mapping of mucin 1, transmembrane (MUC1) among cattle, river buffalo, sheep and goat chromosomes: comparison between bovine chromosome 3 and human chromosome 1.
Four bovine BAC clones (0494F01, 0069D07, 0060B06, and 0306A12) containing MUC1, as confirmed by mapping MUC1 on a RH3000 radiation hybrid panel, were hybridised on R-banded chromosomes of cattle (BTA), river buffalo (BBU), sheep (OAR) and goat (CHI). MUC1 was FISH-mapped on BTA3q13, BBU6q13, OAR1p13 and CHI3q13 and both chromosomes and chromosome bands were homoeologous confirming the high degree of chromosome homoeologies among bovids and adding more information on the pericentromeric regions of these species' chromosomes. Indeed, MUC1 was more precisely assigned to BTA3 and assigned for the first time to BBU6, OAR1p and CHI3. Moreover, detailed and improved cytogenetic maps of BTA3, CHI3, OAR1p and BBU6 are shown and compared with HSA1.
