Anti-PHACTR4 antibodies are used in the immunodetection of the protein phosphatase and actin regulator 4. In humans, the canonical protein has a reported length of 702 amino acid residues and a mass of 78.2 kDa. Its subcellular localization is in the cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Phosphatase and actin regulator protein family, PHACTR4 is a reported regulator of protein phosphatase 1 (PP1) required for neural tube and optic fissure closure, and enteric neural crest cell (ENCCs) migration during development. Synonyms for this target antigen include protein phosphatase 1, regulatory subunit 124. PHACTR4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PHACTR4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
