These factors work with co-activators to direct transcriptional initiation by the RNA polymerase II apparatus. The protein encoded by this gene is a subunit of the CRSP (cofactor required for SP1 activation) complex, which, along with TFIID, is required for efficient activation by SP1. This protein is also a component of other multisubunit complexes e.g. thyroid hormone receptor-(TR-) associated proteins which interact with TR and facilitate TR function on DNA templates in conjunction with initiation factors and cofactors. This protein contains a bipartite nuclear localization signal. This gene is known to escape chromosome X-inactivation. ==Interactions== MED14 has been shown to [interact](/source/Protein-protein_interaction) with [PPARGC1A](/source/PPARGC1A),{{cite journal |last=Wallberg |first=Annika E |author2=Yamamura Soichiro |author3=Malik Sohail |author4=Spiegelman Bruce M |author5=Roeder Robert G |date=Nov 2003 |title=Coordination of p300-mediated chromatin remodeling and TRAP/mediator function through coactivator PGC-1alpha |journal=Mol.
