MED23 (Mediator of RNA polymerase II transcription subunit 23) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Breast cancer. 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

Required for transcriptional activation subsequent to the assembly of the pre-initiation complex. Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional pre-initiation complex with RNA polymerase II and the general transcription factors. Required for transcriptional activation by adenovirus E1A protein. Required for ELK1-dependent transcriptional activation in response to activated Ras signalling. Location: Nucleus (UniProt). Locus 6q23.2 (HGNC).
