Name | TAF5 RNA polymerase II, TATA box binding protein (TBP)-associated factor, 100kDa |
Description | Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates 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 signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily 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. This gene encodes an integral subunit of TFIID associated with all transcriptionally competent forms of that complex. This subunit interacts strongly with two TFIID subunits that show similarity to histones H3 and H4, and it may participate in forming a nucleosome-like core in the TFIID complex. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015] |
Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nTAF5 is a critical subunit of the general transcription factor TFIID, which is indispensable for the initiation of RNA polymerase II transcription. Studies have demonstrated that TAF5 undergoes reversible post‐translational modification by SUMO-1, and this modification on TAF5 interferes with the ability of TFIID to bind promoter DNA. Such reversible SUMO conjugation points to a regulatory mechanism that modulates the promoter-binding activity of TFIID, thereby finely tuning transcription initiation in response to cellular cues."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "TAF5 also plays an essential architectural role in assembling the multi-megadalton TFIID complex. Structural analysis of a TAF5 domain has revealed an alpha-helical configuration with conserved clefts and a capacity to form flexible, extended dimers—features that are critical for the proper assembly and stability of TFIID. These structural properties not only facilitate interactions with other subunits and transcription regulators but also contribute to a coordinated assembly process critical for effective transcription initiation."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Michaël Boyer-Guittaut, Kivanç Birsoy, Corinne Potel, et al.
