Summaries for PCK1 Gene

Entrez Gene Summary for PCK1 Gene

  • This gene is a main control point for the regulation of gluconeogenesis. The cytosolic enzyme encoded by this gene, along with GTP, catalyzes the formation of phosphoenolpyruvate from oxaloacetate, with the release of carbon dioxide and GDP. The expression of this gene can be regulated by insulin, glucocorticoids, glucagon, cAMP, and diet. Defects in this gene are a cause of cytosolic phosphoenolpyruvate carboxykinase deficiency. A mitochondrial isozyme of the encoded protein also has been characterized. [provided by RefSeq, Jul 2008]

GeneCards Summary for PCK1 Gene

PCK1 (Phosphoenolpyruvate Carboxykinase 1) is a Protein Coding gene. Diseases associated with PCK1 include Phosphoenolpyruvate Carboxykinase Deficiency, Cytosolic and Pepck 1 Deficiency. Among its related pathways are Estrogen Receptor Pathway and Glycosaminoglycan metabolism. Gene Ontology (GO) annotations related to this gene include GTP binding and GDP binding. An important paralog of this gene is PCK2.

UniProtKB/Swiss-Prot for PCK1 Gene

  • 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.
