Overlay histogram showing HeLa cells stained with ab57494 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab57494, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

TAF7 also known as transcription initiation factor TFIID subunit 7 plays a critical role in transcription initiation. This protein is approximately 61 kDa in mass. TAF7 is a component of the TFIID complex which is important in assembling the pre-initiation complex necessary for RNA polymerase II to initiate transcription. TAF7 expression is widespread with high expression levels observed in various tissues including the liver and muscle.
Biological function summary

TAF7 functions as an integral part of the TFIID complex. The TFIID complex consisting of TATA-binding protein (TBP) and multiple TBP-associated factors (TAFs) is essential for the accurate transcription of genes by RNA polymerase II. TAF7 influences the assembly and stability of the TFIID complex thereby affecting the transcriptional regulation. It not only interacts directly with other TAFs such as TAF1 and TAF5 but also serves as a regulatory checkpoint in the transition from transcription initiation to elongation.

Pathways

The TAF7 protein acts significantly within the transcription initiation pathway. This pathway is vital for the expression of eukaryotic genes. TAF7 through its interaction with TAF1 and other TAFs contributes to the formation of the pre-initiation complex. By doing so it ensures the proper positioning of RNA polymerase II and the commencement of mRNA synthesis. It also plays a role in pathways controlling cell cycle regulation and development by influencing gene expression critical for growth and cellular responses.

Altered expression or mutations in TAF7 are linked to specific cancers like hepatocellular carcinoma demonstrating its importance in cell proliferation and survival. Furthermore due to its role in gene regulation TAF7 abnormalities can relate to neurodevelopmental disorders. Proteins such as TAF1 have shown connections to disorders linked to transcriptional dysregulation highlighting the interconnected nature of transcription components like TAF7 in various pathological conditions.

Target data

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 : 10438527, PubMed : 33795473). TAF7 forms a promoter DNA binding subcomplex of TFIID, together with TAF1 and TAF2 (PubMed : 33795473). Part of a TFIID complex containing TAF10 (TFIID alpha) and a TFIID complex lacking TAF10 (TFIID beta) (PubMed : 10438527).
