Enables glucuronosyltransferase activity. Involved in several processes, including 4-chlorobiphenyl metabolic process; cellular response to glucocorticoid stimulus; and response to lipopolysaccharide. Located in intracellular membrane-bounded organelle. Part of protein-containing complex. Biomarker of type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in hepatitis B. Orthologous to human UGT1A6 (UDP glucuronosyltransferase family 1 member A6). [provided by Alliance of Genome Resources, Apr 2022]
