Description | CpG WIZ® MGMT - Methylation specific PCR assay |
Overview | Methylation of cytosines located 5' to guanosine is known to have a profound effect on the expression of several eukaryotic genes (Bird, 1992). In normal cells, methylation occurs predominantly in CG-poor regions, while CG-rich areas, called CpG islands, remain unmethylated. Aberrant methylation of normally unmethylated CpG islands has been documented as a relatively frequent event in immortalized and transformed cells (Antequera, 1990) and has been associated with transcriptional inactivation of defined tumor suppressor genes in human cancers (Merlo, 1995). O(6)-Methylguanine DNA methyltransferase (MGMT) is an example of a gene that exhibits characteristic hypermethylation. Methylation-specific PCR (MSP) is a new technology for sensitive detection of abnormal gene methylation utilizing small amounts of DNA (Herman, 1996). This process employs an initial bisulfite reaction to modify the DNA, followed by PCR amplification with specific primers designed to distinguish methylated from unmethylated DNA. |

UniProt Summary | FUNCTION: SwissProt: P16455 # Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) in DNA. Repairs alkylated guanine in DNA by stoichiometrically transferring the alkyl group at the O-6 position to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated. COFACTOR: Binds 1 zinc ion. SIZE: 207 amino acids; 21646 Da SUBCELLULAR LOCATION: Nucleus. SIMILARITY: SwissProt: P16455 ## Belongs to the MGMT family. |
