Anti-PP4R2 antibodies enable researchers to detect and measure the PP4R2 antigen in biological samples. This target is a reported synonym of the PPP4R2 gene, which encodes protein phosphatase 4 regulatory subunit 2. This protein is known to function in mRNA processing and RNA splicing, among other biological roles. The human version of PP4R2 has a canonical amino acid length of 417 residues and a protein mass of 46.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. PP4R2 is a member of the PPP4R2 protein family.
