Preparation and Storage

Background: MED4

MED4 (Mediator complex 4 subunit; also DRIP36) is a 34‑36 kDa member of the mediator complex subunit 4 family of proteins. It is part of a 20+ subunit complex named Mediator that serves as a bridge between RNA polymerase II and DNA binding regulatory proteins that cooperate during RNA synthesis. Human MED4 is 270 amino acids (aa) in length and contains two N-terminal coiled-coil regions (aa 24‑48 and 90‑131) plus a C-terminal poly-Ser region (aa 262‑269). Multiple splice variants may exist. There is an alternate start site at Met47 that may be accompanied by a premature truncation after Asp239. There is also a form with a six aa substitution for aa 105‑270, and a fourth form that shows a 19 aa substitution for aa 1‑41, accompanied by a truncation after Thr260. Over aa 80‑261, human MED4 is 97% aa identical to mouse MED4.
