The mouse gene for phenol UDP-glucuronosyltransferase (UDPGT; Ugtla1)
was mapped at 42 cM on chromsome 1, a position identical to that of th
e gene for bilirubin UDPGT (Ugtla1), from linkage analysis of a three-
point cross test with Idh-1, En-1 and Ugtla1 as marker genes. The cDNA
s for mouse phenol and bilirubin UDPGTs, isolated after amplification
by PCR, shared an identical 3'-half region. Our results strongly sugge
st that mouse bilirubin and phenol UDPGTs are expressed from a single
gene and involve alternative splicing events. We also detected duplica
tion of the gene for phenol UDPGT in all mouse strains examined with t
he exception of MOL-MIT and SUB-SHH.
