Anti-protein phosphatase 1, regulatory (inhibitor) subunit 3C antibodies enable researchers to detect and measure the protein phosphatase 1, regulatory (inhibitor) subunit 3C antigen in biological samples. This target is a reported synonym of the PPP1R3C gene, which encodes protein phosphatase 1 regulatory subunit 3C. This protein is known to function in metabolic processes, among other biological roles. The human version of protein phosphatase 1, regulatory (inhibitor) subunit 3C has a canonical amino acid length of 317 residues and a protein mass of 36.4 kilodaltons. Other names for this target antigen include PPP1R5, PTG, and PP1 subunit R5.
