一般說明
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.
特異性
MGMT is a 22 kDa DNA repair protein that is present in all normal tissues; however, in a subset of human tumours MGMT is completely absent. Thus, antibody MAB16200 may be helpful in utilizing MGMT as a marker of malignant or pre-malignant cells. Because MGMT repairs the potentially cytotoxic antitumour lesions induced in DNA by certain cancer chemotherapeutic alkylating agents (e.g. BCNU, CCNU, DTIC, procarbazinc, temozolomide), tumours lacking or having low levels of MGMT will predictably be responsive to drug therapy. Conversely, tumours with high MGMT levels will likely be drug resistant. The MGMT antibody may also be used to gauge the effectiveness of MGMT modulators, such as O-6-benzylguanine, which lead to rapid degradation of the inactivated protein.
免疫原
Made against recombinant human MGMT (O-6-methylguanine-DNA methyltransferase) expressed in E. coli.
