Anti-TCERG1 antibodies are used in the immunodetection of the protein transcription elongation regulator 1. In humans, the canonical protein has a reported length of 1098 amino acid residues and a mass of 123.9 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the brain neurons. TCERG1 is reported to be a transcription factor that binds RNA polymerase II and inhibits the elongation of transcripts from target promoters. Synonyms for this target antigen include TAF2S, Urn1, TATA box binding protein (TBP)-associated factor, RNA polymerase II, S, 150kD, TATA box-binding protein-associated factor 2S, co-activator of 150 kDa, and CA150. TCERG1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of TCERG1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
