Anti-PRR19 antibodies are used in the immunodetection of the protein proline rich 19. In humans, the canonical protein has a reported length of 356 amino acid residues and a mass of 38.7 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. PRR19 is reported to promote meiotic crossing over formation through its interaction with CNTD1 by participating in the crossover differentiation step of crossover-specific recombination intermediates. Synonyms for this target antigen include proline-rich protein 19. PRR19 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Western Blot is the most common application for the PRR19 antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
