Previous GeneCards Identifiers for MGMT Gene
Alkylating agents are potent carcinogens that can result in cell death, mutation and cancer. The protein encoded by this gene is a DNA repair protein that is involved in cellular defense against mutagenesis and toxicity from alkylating agents. The protein catalyzes transfer of methyl groups from O(6)-alkylguanine and other methylated moieties of the DNA to its own molecule, which repairs the toxic lesions. Methylation of the genes promoter has been associated with several cancer types, including colorectal cancer, lung cancer, lymphoma and glioblastoma. [provided by RefSeq, Sep 2015]
GeneCards Summary for MGMT Gene
MGMT (O-6-Methylguanine-DNA Methyltransferase) is a Protein Coding gene. Diseases associated with MGMT include Oligodendroglioma and Gliosarcoma. Among its related pathways are DNA Damage and Chks in Checkpoint Regulation. Gene Ontology (GO) annotations related to this gene include calcium ion binding and damaged DNA binding.
UniProtKB/Swiss-Prot Summary for MGMT Gene
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.
Protein arginine methyltransferases are enyzmes that catalyze the transfer of methyl groups from S-adenosylmethionine (SAM) to the arginine residues on histones and other proteins. The dysregulation of this methylation is critical in the development of certain cancers.
