OnCo

MECOM (Histone-lysine N-methyltransferase MECOM) is a protein that switches other genes on and off. The public catalogues list it as an oncogene driver, a tumour suppressor, a biomarker and a fusion partner, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Breast cancer, Prostate cancer, Endometrial 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

Functions as a transcriptional regulator binding to DNA sequences in the promoter region of target genes and regulating positively or negatively their expression. Oncogene which plays a role in development, cell proliferation and differentiation. May also play a role in apoptosis through regulation of the JNK and TGF-beta signalling. Involved in haematopoiesis. Displays histone methyltransferase activity and monomethylates 'Lys-9' of histone H3 (H3K9me1). Probably catalyses the monomethylation of free histone H3 in the cytoplasm which is then transported to the nucleus and incorporated into nucleosomes where SUV39H methyltransferases use it as a substrate to catalyse histone H3 'Lys-9' trimethylation. Location: Nucleus; Nucleus speckle; Cytoplasm (UniProt). Locus 3q26.2 (HGNC).
