Function

The TFIID basal transcription factor complex plays a major role in the initiation of RNA polymerase II (Pol II)-dependent transcription (PubMed:33795473). TFIID recognizes and binds promoters with or without a TATA box via its subunit TBP, a TATA-box-binding protein, and promotes assembly of the pre-initiation complex (PIC) (PubMed:33795473). The TFIID complex consists of TBP and TBP-associated factors (TAFs), including TAF1, TAF2, TAF3, TAF4, TAF5, TAF6, TAF7, TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13 (PubMed:33795473). The TFIID complex structure can be divided into 3 modules TFIID-A, TFIID-B, and TFIID-C (PubMed:33795473). TAF3 forms the TFIID-A module together with TAF5 and TBP (PubMed:33795473). Required in complex with TBPL2 for the differentiation of myoblasts into myocytes (PubMed:11438666). The TAF3-TBPL2 complex replaces TFIID at specific promoters at an early stage in the differentiation process (PubMed:11438666).

Activity summary

TAF3 also known as TATA-box binding protein associated factor 3 is an important component of the transcription factor IID (TFIID) complex. This protein weighs approximately 98 kDa. It is expressed in various tissues with high expression in the brain and testis. TAF3 interacts directly with the core promoter elements in DNA enabling the accurate initiation of transcription by RNA polymerase II. This interaction is stabilized by the YEATS domain within TAF3 which binds acetylated histones thereby playing a role in the regulation of transcription elongation.

Biological function summary

TAF3 plays an essential role in cellular processes involving transcriptional regulation and chromatin structure modification. TAF3 is part of the larger TFIID complex which is necessary for the initiation of transcription by RNA polymerase II. It acts by binding specific DNA elements thereby facilitating the recruitment of additional transcription machinery. The presence of the YEATS domain enables TAF3 to bind to modified histones which can alter chromatin architecture to promote gene expression.

Pathways

TAF3 functions within the transcription initiation pathway involving RNA polymerase II. TFIID which includes TAF3 positions itself at the core promoter of genes making it an integral part of RNA polymerase II-dependent transcription regulation. Its interactions are significant in the Wnt signaling pathway in which it facilitates the expression of target genes. In this context TAF3 works alongside proteins like TATA-binding protein (TBP) and other TAFs (TBP-associated factors) to ensure proper transcriptional activation.

Associated diseases and disorders

TAF3 holds relevance in cancer and neurological disorders. Its role in the transcriptional regulation of genes critical for cell proliferation and differentiation can have implications for tumorigenesis. Aberrant expression of TAF3 is linked to certain forms of cancer where deregulation of transcriptional initiation pathways can lead to uncontrolled cell growth. Furthermore TAF3's involvement in transcriptional modulation makes it a candidate in studying neurodegenerative diseases potentially through interactions with proteins that influence neural gene expression and stability such as histone modifications.
