Protein Name: Methylated-DNA--protein-cysteine methyltransferase

UniprotKB/SwissProt ID: P16455 (P16455)

Gene Name: MGMT

Organism: Homo sapiens (Human)

Function: Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) and O4-methylthymine (O4-MeT) in DNA. Repairs the methylated nucleobase in DNA by stoichiometrically transferring the methyl group to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Nucleus
