Anti-SH3RF1 antibodies are used in the immunodetection of the protein SH3 domain containing ring finger 1. In humans, the canonical protein has a reported length of 888 amino acid residues and a mass of 93.1 kDa. Its subcellular localization is in the Golgi and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the SH3RF protein family, SH3RF1 is known to have E3 ubiquitin-protein ligase activity. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include RING-type E3 ubiquitin transferase SH3RF1, SH3 domain-containing RING finger protein 1, SH3 multiple domains 2, SH3 multiple domains protein 2, and E3 ubiquitin-protein ligase SH3RF1. SH3RF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SH3RF1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
