MED28

Mediator of RNA polymerase II transcription subunit 28 is an enzyme that in humans is encoded by the MED28 gene.[5][6][7] It forms part of the Mediator complex.

Function

Subunit Med28 of the Mediator may function as a scaffolding protein within Mediator by maintaining the stability of a submodule within the head module, and components of this submodule act together in a gene-regulatory programme to suppress smooth muscle cell differentiation. Thus, mammalian Mediator subunit Med28 functions as a repressor of smooth muscle-cell differentiation, which could have implications for disorders associated with abnormalities in smooth muscle cell growth and differentiation, including atherosclerosis, asthma, hypertension, and smooth muscle tumours.[8]

Interactions


MED28 has been shown to interact with Merlin,[6] Grb2[6] and MED26.[9]
