Anti-TAF7-like RNA polymerase II, TATA box binding protein (TBP)-associated factor, 50kDa antibodies enable researchers to detect and measure the TAF7-like RNA polymerase II, TATA box binding protein (TBP)-associated factor, 50kDa antigen in biological samples. This target is a reported synonym of the TAF7L gene, which encodes TATA-box binding protein associated factor 7 like. This protein is known to function in cell differentiation and spermatogenesis, among other biological roles. The human version of TAF7-like RNA polymerase II, TATA box binding protein (TBP)-associated factor, 50kDa has a canonical amino acid length of 462 residues and a protein mass of 52.6 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells. Other names for this target antigen include CT40, TAF2Q, and transcription initiation factor TFIID subunit 7-like.
