Anti-SH3BGR antibodies are used in the immunodetection of the protein SH3 domain binding glutamate rich protein. In humans, the canonical protein has a reported length of 239 amino acid residues and a mass of 26.1 kDa. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the heart and skeletal muscle. It is a member of the SH3BGR protein family. Synonyms for this target antigen include SH3 domain-binding glutamic acid-rich protein, SH3-binding domain and glutamic acid-rich protein, and 21-GARP. SH3BGR gene orthologs have been reported in the mouse, bovine and chimpanzee species. Some SH3BGR antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
