Anti-TAF4B antibodies are used in the immunodetection of the protein TATA-box binding protein associated factor 4b. In humans, the canonical protein has a reported length of 862 amino acid residues and a mass of 91.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is found to be highly expressed in ovarian granulosa cells. A member of the TAF4 protein family, TAF4B is known to be involved with protein phosphorylation and spermatogenesis. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include TAF2C2, TAFII105, transcription initiation factor TFIID subunit 4B, TAF(II)105, and SPGF13. TAF4B gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the TAF4B antibodies listed below. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
