This gene encodes a TAF (TATA box-binding protein-associated factor), which associates with TBP (TATA box-binding protein) to form the B-TFIID complex that is required for transcription initiation of genes by RNA polymerase II. This TAF has DNA-dependent ATPase activity, which drives the dissociation of TBP from DNA, freeing the TBP to associate with other TATA boxes or TATA-less promoters.Store at -20°C or lower. Aliquot to avoid repeated freezing and thawing. *   http://www.creative-diagnostics.com/Anti-BTAF1-PAb-191893-147.htm
