The PPCA ELISA kits listed below are analytical tools for measuring concentrations of PPCA in various samples. PPCA is an alternative name for the human CTSA gene, which encodes the protein, cathepsin A. It has been mentioned that PPCA plays a role in intracellular protein transport and proteolysis, among other functions. Structurally, the CTSA protein is 480 amino acid residues in length and 54.5 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the lysosomes of the cell. This protein is known to be glycosylated. Other names for this target antigen include GLB2, GSL, and NGBE.
