Anti-CDPS antibodies are protein reagents that detect specific antigens. The CDPS antigen is another term for the human protein calpain small subunit 1, encoded by the CAPNS1 gene. The protein is a regulatory subunit of the calcium-regulated non-lysosomal thiol-protease which catalyzes limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Canonically, it has an amino acid length of 268 residues and a mass of 28.3 kilodaltons. Its subcellular localization is in the cell membrane and cytoplasm and it is widely expressed in many tissue types. Other alias names for CDPS include CALPAIN4, CALPAIN4, and CANP. Indicated applications for CDPS antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
