Mediator of RNA polymerase II transcription subunit 14 is an enzyme that in humans is encoded by the MED14 gene.[5][6][7]

The activation of gene transcription is a multistep process that is triggered by factors that recognize transcriptional enhancer sites in DNA. 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.[7]

Interactions

MED14 has been shown to interact with PPARGC1A,[8] Estrogen receptor alpha,[9] STAT2,[10] Cyclin-dependent kinase 8,[11][12] Glucocorticoid receptor[13] and Hepatocyte nuclear factor 4 alpha.[14][15]
