Anti-SPDYC antibodies are used in the immunodetection of the protein speedy/RINGO cell cycle regulator family member C. In humans, the canonical protein has a reported length of 293 amino acid residues and a mass of 33.2 kDa. Its subcellular localization is in the cytoplasm. It is reported to be expressed in a variety of tissues including bone marrow, kidney, small intestine, liver, placenta and testis. A member of the Speedy/Ringo protein family, SPDYC is reported to promote progression through the cell cycle via binding and activation of CDK1 and CDK2. Synonyms for this target antigen include RINGO C, hSpy/Ringo C, rapid inducer of G2/M progression in oocytes C, speedy homolog C, and speedy protein C. SPDYC gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. These SPDYC antibodies are widely used in Immunohistochemistry experiments, among other applications.
