Clone Host Grade Applications
Monoclonal Mouse Affinity Purified B IP IH FC IF
O6-Methylguanine-DNA Methyltransferase (MGMT) is a ubiquitous DNA repair protein that removes O6-alkyl-guanine, primarily O6 methylguanine lesions from damaged DNA. It is a major contributor to cellular protection from the mutagenic, carcinogenic, and cytotoxic effects of DNA alkylation. The mechanism of MGMT action is based on the transfer of the alkyl group from the DNA to a unique acceptor cysteine residue in the protein, forming a stable thioether linkage. MGMT is frequently classified as a suicide protein. The repair capacity for O6- methylguanine is dependent on the number of MGMT molecules in the cell. There is a correlation between the occurrence of cancer in various tissues and the lack of the MGMT enzyme. High levels of MGMT result in reduced tumor events and resistance of tumors to alkylating agents.
