Anti-Sorting Nexin 3 antibodies are used for the immunodetection of the protein encoded by the SNX3 gene. In humans, the canonical protein has a reported length of 162 amino acid residues and a mass of 18.8 kDa. Its subcellular localization is in the cytoplasmic vesicles. Alternative splicing is reported to yield 4 different isoforms for this protein. A member of the Sorting nexin protein family, it is known to be a phosphoinositide-binding protein required for multivesicular body formation. Post-translational modifications have been described, including ubiquitination. Other names for this target antigen include MCOPS8, SDP3, sorting nexin 3A, and Grd19. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Sorting Nexin 3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
