Provided below are ELISA kits targeting protein phosphatase 4 catalytic subunit, a human protein encoded by PPP4C. This protein is 307 amino acids long, with a mass of 35.1 kDa, and is a member of the PPP phosphatase family, PP-4 (PP-X) subfamily. This is reported to be a cytoplasmic and nuclear protein. It is also an enzyme classified as a(n) protein-serine/threonine phosphatase. Other alias names for this protein include: serine/threonine-protein phosphatase 4 catalytic subunit, protein phosphatase 4 (formerly X) catalytic subunit, protein phosphatase X catalytic subunit, PP-X, PP4C, PPH3, and PPP4.
