General description
Phosphoenolpyruvate carboxykinase, cytosolic (UniProt: also known as PEPCK, PEPCK-C) is encoded by the PCK1 (also known as PEPCK1) gene (Gene ID: 5105) in human. PEPCK catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), which is a rate-limiting step in gluconeogenesis. It requires manganese as a cofactor. It is expressed in higher levels in liver of fasting subjects. Kidney and adipocytes exhibit lower expression levels. Two isozymes of PEPCK have been identified, cytosolic and mitochondrial. PEPCK consists of an N-terminal and a catalytic C-terminal domain, with the active site and metal ions located in a cleft between them. Upon binding to substrate, PEPCK undergoes a conformational change that accelerates the catalysis process. Expression of PEPCK can be controlled by cAMP, glucocorticoids, and by insulin. Its expression is induced by glucagon, catecholamines, and glucocorticoids during periods of fasting and in response to stress and is diminished following glucose-induced and by the action of insulin. PEPCK-C is absent in fetal liver but appears at birth, concomitant with the capacity for gluconeogenesis. Deficiency of PEPCK-C is a rare metabolic disorder results in fatty infiltration of liver and kidney, hypoglycemia, hepatomegaly, and failure to thrive.
~65 kDa observed; 69.19 kDa calculated. Uncharacterized bands may be observed in some lysate(s).
