TAF4 antibody

Background of TAF4 antibody

Initiation of transcription by R polymerase II requires the activities of more than 70 polypeptides. The protein that coordites these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory sigls. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutiorily conserved proteins known as TBP-associated factors or TAFs. TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation. TAF4 is one of the larger subunits of TFIID that has been shown to potentiate transcriptiol activation by retinoic acid, thyroid hormone and vitamin D3 receptors. In addition, this subunit interacts with the transcription factor CREB, which has a glutamine-rich activation domain, and binds to other proteins containing glutamine-rich regions. Aberrant binding to this subunit by proteins with expanded polyglutamine regions has been suggested as one of the pathogenetic mechanisms underlying a group of neurodegenerative disorders referred to as polyglutamine diseases.Initiation of transcription by R polymerase II requires the activities of more than 70 polypeptides.
