MGMT Gene Function

O-6-Methylguanine-DNA Methyltransferase

ProteinCurated

Overview

MGMT directly reverses O6-alkylguanine DNA damage by transferring the alkyl group to itself. Promoter methylation can reduce MGMT expression in glioma, but methylation assays, cut-offs and tumour context must remain attached to any result.

Common Questions About MGMT

What does MGMT do?

MGMT participates in Direct DNA-damage reversal, Alkylation-damage response, Epigenetic gene regulation. MGMT directly reverses O6-alkylguanine DNA damage by transferring the alkyl group to itself. Promoter methylation can reduce MGMT expression in glioma, but methylation assays, cut-offs and tumour context must remain attached to any result.

Why is MGMT relevant to cancer research?

Its reported relevance includes Glioblastoma, Diffuse glioma, Alkylator-treated cancers. The exact alteration, assay and disease context determine what a result can support.
