Anti-phosphatidic acid phosphatase type 2C antibodies enable researchers to detect and measure the phosphatidic acid phosphatase type 2C antigen in biological samples. This target is a reported synonym of the PLPP2 gene, which encodes phospholipid phosphatase 2. This protein is known to function in the metabolism of lipids and signal transduction pathways, among other biological roles. The human version of phosphatidic acid phosphatase type 2C has a canonical amino acid length of 288 residues and a protein mass of 32.6 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the ER and cell membrane of cells. Other names for this target antigen include LPP2, LPP2, and PAP-2c.
