Chromosomal and regional localization of the genes for UMPH2, APRT, PEPD, PEPS, PSP, and PGP in mink: comparison with man and mouse.
Segregation of mink biochemical markers uridine 5'-monophosphate phosphohydrolase-2 (UMPH2), adenine phosphoribosyltransferase (APRT), phosphoserine phosphatase (PSP), phosphoglycolate phosphatase (PGP), peptidases D (PEPD) and S (PEPS), as well as mink chromosomes, was investigated in a set of mink x mouse hybrid clones. The results obtained allowed us to make the following mink gene assignments: UMPH2, chromosome 8; PEPD and APRT, chromosome 7; PEPS, chromosome 6; and PSP and PGP, chromosome 14. The latter two genes are the first known markers for mink chromosome 14. For regional mapping, UMPH2 was analyzed in mouse cell clones transformed by means of mink metaphase chromosomes (Gradov et al., 1985) and also in mink x mouse hybrid clones carrying fragments of mink chromosome 8 of different sizes. Based on the data obtained, the gene for UMPH2 was assigned to the region 8pter----p26 of mink chromosome 8. The present data is compared with that previously established for man and mouse with reference to the conservation of syntenic gene groups and G-band homoeologies of chromosomes in mammals.
