GENE INFORMATION
Gene name	PCK2 (HGNC Symbol)
Synonyms	PEPCK, PEPCK2
Description	Phosphoenolpyruvate carboxykinase 2 (mitochondrial) (HGNC Symbol)
Entrez gene summary	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.
