Anti-PLEKHA1 antibodies are used in the immunodetection of the protein pleckstrin homology domain containing A1. In humans, the canonical protein has a reported length of 404 amino acid residues and a mass of 45.6 kDa. Its subcellular localization is in the cell membrane, nucleus, and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in skeletal muscle, thymus, pancreas, placenta and lung. PLEKHA1 is known to bind specifically to phosphatidylinositol 3,4-diphosphate (PtdIns3,4P2), but not to other phosphoinositides. Synonyms for this target antigen include pleckstrin homology domain containing, family A (phosphoinositide binding specific) member 1, tandem PH domain-containing protein 1, and pleckstrin homology domain-containing family A member 1. PLEKHA1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PLEKHA1 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.
