Mediator of RNA polymerase II transcription subunit 27 is an enzyme that in humans is encoded by the MED27 gene.[3][4] It forms part of the Mediator complex.
The ubiquitous expression of Med27 mRNA suggests a universal requirement for Med27 in transcriptional initiation. Loss of Crsp34/Med27 decreases amacrine cell number, but increases the number of rod photoreceptor cells.[5]
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.[4]
