Predicted to enable UDP-glucose 4-epimerase activity and protein homodimerization activity. Predicted to be involved in galactose catabolic process via UDP-galactose. Predicted to act upstream of or within galactose metabolic process. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in galactose epimerase deficiency. Orthologous to human GALE (UDP-galactose-4-epimerase). [provided by Alliance of Genome Resources, Apr 2022]
