Predicted to enable S-adenosyl-L-methionine binding activity and thiopurine S-methyltransferase activity. Involved in response to testosterone. Predicted to be located in cytoplasm. Human ortholog(s) of this gene implicated in acute lymphoblastic leukemia; alopecia; leukopenia; and thiopurine S-methyltransferase deficiency. Orthologous to human TPMT (thiopurine S-methyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
