Enables alpha-methylacyl-CoA racemase activity. Involved in bile acid biosynthetic process. Located in mitochondrion and peroxisome. Human ortholog(s) of this gene implicated in alpha-methylacyl-CoA racemase deficiency; congenital bile acid synthesis defect 4; and urinary bladder cancer. Orthologous to human AMACR (alpha-methylacyl-CoA racemase). [provided by Alliance of Genome Resources, Apr 2022]
