Anti-PPFIA4 antibodies are used in the immunodetection of the protein PTPRF interacting protein alpha 4. In humans, the canonical protein has a reported length of 1185 amino acid residues and a mass of 134.4 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is found to be preferentially expressed in the heart, brain, and skeletal muscle. A member of the Liprin protein family, PPFIA4 is believed to regulate the disassembly of focal adhesions. Synonyms for this target antigen include protein tyrosine phosphatase, receptor type, f polypeptide (PTPRF), interacting protein (liprin), alpha 4, and liprin-alpha-4. PPFIA4 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the PPFIA4 antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
