Anti-GTF2A1 antibodies are used in the immunodetection of the protein general transcription factor IIA subunit 1. In humans, the canonical protein has a reported length of 376 amino acid residues and a mass of 41.5 kDa. Its subcellular localization is in the nucleus. A member of the TFIIA subunit 1 protein family, GTF2A1 is known to be involved with transcription by RNA polymerase II. Post-translational modifications have been described, including protein cleavage. Synonyms for this target antigen include TFIIA, TFIIA-42, TFIIAL, transcription initiation factor IIA subunit 1, TFIIA alpha/beta subunits, and TF2A1. GTF2A1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the GTF2A1 antibodies listed below. ELISA and Immunocytochemistry are also common applications.
