Anti-proline rich 5 antibodies are used for the immunodetection of the protein encoded by the PRR5 gene. In humans, the canonical protein has a reported length of 388 amino acid residues and a mass of 42.8 kDa. Alternative splicing is reported to yield 5 different isoforms for this protein. It is notably expressed in the kidney and liver. A member of the PROTOR protein family, it is known to be involved with the cell cycle and cytoskeleton organization. Other names for this target antigen include proline rich 5 (renal), protein observed with Rictor-1, and proline-rich protein 5. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some proline rich 5 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
