Summary
PCK2 (phosphoenolpyruvate carboxykinase 2, mitochondrial, HGNC:8725) is a protein-coding gene on chromosome 14q11.2-q12, encoding Phosphoenolpyruvate carboxykinase [GTP], mitochondrial (Q16822). Mitochondrial phosphoenolpyruvate carboxykinase that catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic pathway that produces glucose from lactate and other precursors derived from the citric acid cycle.
This gene encodes a mitochondrial enzyme that catalyzes the conversion of oxaloacetate to phosphoenolpyruvate in the presence of guanosine triphosphate (GTP). A cytosolic form of this protein is encoded by a different gene and is the key enzyme of gluconeogenesis in the liver. Alternatively spliced transcript variants have been described.

UniProt curated annotations — full annotation on UniProt →
Function. Mitochondrial phosphoenolpyruvate carboxykinase that catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic pathway that produces glucose from lactate and other precursors derived from the citric acid cycle. Can play an active role in glyceroneogenesis and gluconeogenesis. Also acts as a serine/threonine-protein kinase: phosphorylates and activates ACSL4, thereby promoting ferroptosis.
Subunit / interactions. Monomer.
Subcellular location. Mitochondrion.
Tissue specificity. Widely expressed.
Disease relevance. Mitochondrial phosphoenolpyruvate carboxykinase deficiency (M-PEPCKD) [MIM:261650] Metabolic disorder resulting from impaired gluconeogenesis. It is a rare disease with less than 10 cases reported in the literature. Clinical characteristics include hypotonia, hepatomegaly, failure to thrive, lactic acidosis and hypoglycemia. Autopsy reveals fatty infiltration of both the liver and kidneys. The disorder is transmitted as an autosomal recessive trait. The gene represented in this entry may be involved in disease pathogenesis.
Cofactor. Binds 1 Mn(2+) ion per subunit.
Pathway. Carbohydrate biosynthesis; gluconeogenesis.
Miscellaneous. In eukaryotes there are two isozymes: a cytoplasmic one and a mitochondrial one.
Similarity. Belongs to the phosphoenolpyruvate carboxykinase [GTP] family.
