Anti-TAF1D antibodies are used in the immunodetection of the protein TATA-box binding protein associated factor, RNA polymerase I subunit D. In humans, the canonical protein has a reported length of 278 amino acid residues and a mass of 32.1 kDa. Its subcellular localization is in the nucleus. TAF1D is a known component of the transcription factor SL1/TIF-IB complex, which is involved in the assembly of the PIC (preinitiation complex) during RNA polymerase I-dependent transcription. Synonyms for this target antigen include RNA polymerase I-specific TBP-associated factor 41 kDa, TATA box binding protein (TBP)-associated factor, RNA polymerase I, D, 41kDa, TATA box-binding protein-associated factor 1D, and Josephin domain containing 3. TAF1D gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the TAF1D antibodies listed below. ELISA, Flow Cytometry, and Immunohistochemistry are also common applications.
