abstract：:The UGT1 locus is felt to be highly conserved between species, as is evident from the characterization of the locus in rodents and humans. In rabbits, cDNAs encoding proteins homologous to human UGT1A4, UGT1A6, and UGT1A7 have previously been identified. Here we demonstrate by Southern blot analysis, using exon 1 dive...
