Anti-SPRY3 antibodies are used in the immunodetection of the protein sprouty RTK signaling antagonist 3. In humans, the canonical protein has a reported length of 288 amino acid residues and a mass of 31.2 kDa. Its subcellular localization is in the cytoplasm. It is reported to be widely expressed, particularly in the fetal tissues. A member of the Sprouty protein family, Spry3 is reported to inhibit neurite branching, arbor length and neurite complexity (By similarity). Synonyms for this target antigen include antagonist of FGF signaling, sprouty homolog 3, sprouty3, and protein sprouty homolog 3. SPRY3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some Spry3 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
