Anti-GABPB2 antibodies are used in the immunodetection of the protein GA binding protein transcription factor subunit beta 2. In humans, the canonical protein has a reported length of 448 amino acid residues and a mass of 48.7 kDa. Its subcellular localization is in the nucleus. GABPB2 is believed to function as a transcription factor capable of interacting with purine rich repeats (GA repeats). Synonyms for this target antigen include GA binding protein transcription factor beta subunit 2, GABP subunit beta-2, and GA-binding protein subunit beta-2. GABPB2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some GABPB2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
