Anti-PA2G4 antibodies are used in the immunodetection of the protein proliferation-associated 2G4. In humans, the canonical protein has a reported length of 394 amino acid residues and a mass of 43.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Peptidase M24 protein family, PA2G4 is believed to play a role in a ERBB3-regulated signal transduction pathway. Synonyms for this target antigen include HG4-1, ITAF45, p38-2G4, proliferation-associated protein 2G4, ErbB-3 binding protein 1, and EBP1. PA2G4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of PA2G4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
