MGMT O-6-methylguanine-DNA methyltransferase

ENSG00000170430 · protein coding · Open Targets profile

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.

In 14 of 15 cancers, the evidence for MGMT comes mainly from mutations found in tumours

Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.

Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.8790799975395203 (upper bound 1.3743000030517578). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs
