KMT2D (Histone-lysine N-methyltransferase 2D) is a protein that switches other genes on and off. The public catalogues list it as a drug target, an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Lung cancer, Non-Hodgkin lymphoma, Bladder & urothelial cancer and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Histone methyltransferase that catalyses methyl group transfer from S-adenosyl-L-methionine to the epsilon-amino group of 'Lys-4' of histone H3 (H3K4). Part of chromatin remodeling machinery predominantly forms H3K4me1 methylation marks at active chromatin sites where transcription and DNA repair take place. Acts as a coactivator for oestrogen receptor by being recruited by ESR1, thereby activating transcription. Location: Nucleus (UniProt). Locus 12q13.12 (HGNC).
