Anti-PLPPR2 antibodies are used in the immunodetection of the protein phospholipid phosphatase related 2. In humans, the canonical protein has a reported length of 343 amino acid residues and a mass of 36.9 kDa. Its subcellular localization is in the membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the PA-phosphatase related phosphoesterase protein family, it is known to be involved with the metabolism of lipids and signal transduction pathways. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include inactive phospholipid phosphatase PLPPR2, lipid phosphate phosphatase-related protein type 2, plasticity related gene 4, and phospholipid phosphatase-related protein type 2.
