Anti-PPP1R4 antibodies enable researchers to detect and measure the PPP1R4 antigen in biological samples. This target is a reported synonym of the PPP1R3B gene, which encodes protein phosphatase 1 regulatory subunit 3B. This protein is known to function in metabolic processes, among other biological roles. The human version of PPP1R4 has a canonical amino acid length of 285 residues and a protein mass of 32.7 kilodaltons. It is reported to be widely expressed in many tissue types.
