MED23
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.
Overview
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.
IntOGen calls it a driver in 1 cohort (0 activating, 1 loss-of-function), covering Invasive Breast Carcinoma.

- 2 · What goes wrong in cancer

- 3 · How drugs use it
No product in this corpus aims at MED23 yet. Because the protein is lost rather than overactive, drugs either restore its function or exploit the weakness its loss leaves (synthetic lethality).

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).

Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: IntOGen calls it a loss-of-function (LoF) driver in 1 cohort. Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
