Anti-TATA-box binding protein associated factor, RNA polymerase I, D antibodies enable researchers to detect and measure the TATA-box binding protein associated factor, RNA polymerase I, D antigen in biological samples. This target is a reported synonym of the TAF1D gene, which encodes TATA-box binding protein associated factor, RNA polymerase I subunit D. This protein is known to function in the regulation of transcription, among other biological roles. The human version of TATA-box binding protein associated factor, RNA polymerase I, D has a canonical amino acid length of 278 residues and a protein mass of 32.1 kilodaltons. It is reported to be localized in the nucleus of cells.
