Anti-GABPB1 antibodies are used in the immunodetection of the protein GA binding protein transcription factor subunit beta 1. In humans, the canonical protein has a reported length of 395 amino acid residues and a mass of 42.5 kDa. Its subcellular localization is in the nucleus. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. GABPB1 is reported to be a transcription factor capable of interacting with purine rich repeats (GA repeats). Post-translational modifications have been described, including acetylation. Synonyms for this target antigen include E4TF1, E4TF1-47, E4TF1-53, E4TF1B, GABPB, GABPB2, NRF2B1, and BABPB2. GABPB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of GABPB1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
