MED4

Mediator of RNA polymerase II transcription subunit 4 also known as mediator complex subunit 4 (MED4), a component of Mediator or vitamin D3 receptor-interacting protein complex 36 kDa component (DRIP36) is a is_associated_with::protein that in humans is encoded by the MED4 is_associated_with::gene.

Function
The is_associated_with::protein encoded by this gene is a component of the is_associated_with::vitamin D receptor-interacting protein (DRIP) complex which functions as a is_associated_with::nuclear receptor coactivator. The DRIP complex is capable of activating nuclear receptors in a ligand-dependent manner.

Interactions
MED4 has been shown to interact with is_associated_with::MED25.
