    Summary
    Enables S-adenosylmethionine-homocysteine S-methyltransferase activity. Involved in sulfur amino acid metabolic process. Located in cytoplasm. Human ortholog(s) of this gene implicated in several diseases, including IgA glomerulonephritis; artery disease (multiple); autistic disorder; hematologic cancer (multiple); and hyperhomocysteinemia. Orthologous to human MTR (5-methyltetrahydrofolate-homocysteine methyltransferase). [provided by Alliance of Genome Resources, Dec 2024]
