Anti-PEX5 antibodies are used in the immunodetection of the protein peroxisomal biogenesis factor 5. In humans, the canonical protein has a reported length of 639 amino acid residues and a mass of 70.9 kDa. Its subcellular localization is in the cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably expressed in fetal brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. A member of the Peroxisomal targeting signal receptor protein family, PEX5 is a known receptor that mediates peroxisomal import of proteins containing a C-terminal PTS1-type tripeptide peroxisomal targeting signal (SKL-type). Synonyms for this target antigen include PBD2B, PTS1-BP, PTS1R, PXR1, RCDP5, PTS1 receptor, peroxin-5, and PBD2A. PEX5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PEX5 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
