Anti-Phosphoenolpyruvate Carboxylase antibodies enable researchers to detect and measure the Phosphoenolpyruvate Carboxylase antigen in biological samples. This target is a reported synonym of the PCK1 gene, which encodes phosphoenolpyruvate carboxykinase 1. This protein is known to function in carbohydrate metabolism and homeostasis and insulin signaling pathways, among other biological roles. The human version of Phosphoenolpyruvate Carboxylase has a canonical amino acid length of 622 residues and a protein mass of 69.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the ER and cytoplasm of cells and notably expressed in the rectum, kidney, duodenum, colon, and appendix. Other names for this target antigen include PCKDC, PEPCK-C, and PEPCK1. Western Blot is the most common application for the Phosphoenolpyruvate Carboxylase antibodies listed below. ELISA and Immunohistochemistry are also common applications.
