TAF7 (TATA-box binding protein associated factor 7) gene is localized to human chromosome 5q31. It is a part of the multi-subunit transcription factor TFIID. It was initially recognized as TBP-associated factor (TAFII) of TFIID, which is specific for RNA polymerase II.

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: TAF7 (TATA-box binding protein associated factor 7) acts as a transcriptional repressor, where it binds to TAF1, and prevents its acetyl transferase activity. This activity is necessary for the basal transcription of MHC (major histocompatibility class) I. It acts as a regulator of check-point and prevents premature initiation of transcription until the preinitiation complex (PIC) is assembled completely. It interacts with multiple transcription factors such as, Sp1 (specificity protein), YY1 (Yin Yang 1), USF (upstream transcription factor 1), CTF (C-terminal fragment), adenovirus E1A, and HIV-1 (human immunodeficiency virus) Tat (trans-activator of transcription). It is also involved in the activation of thyroid hormone and vitamin D3 receptor in a ligand-independent fashion. It might also be involved in the processing of the 3' end of mRNA.
