Description:
PCK1(Phosphoenolpyruvate carboxykinase, cytosolic) is also named as PEPCK1 and belongs to the phosphoenolpyruvate carboxykinase [GTP] family. It catalyzes the formation of phosphoenolpyruvate from oxaloacetate, with the release of carbon dioxide and GDP. It is also a main control point for the regulation of gluconeogenesis. In eukaryotes there are two isozymes: a cytoplasmic one and a mitochondrial one. Defects in PCK1 are the cause of cytosolic phosphoenolpyruvate carboxykinase deficiency (C-PEPCKD). This antibody is specific to PCK1.

Research Backgrounds

Function:

Regulates cataplerosis and anaplerosis, the processes that control the levels of metabolic intermediates in the citric acid cycle. At low glucose levels, it catalyzes the cataplerotic 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. At high glucose levels, it catalyzes the anaplerotic conversion of phosphoenolpyruvate to oxaloacetate.

PTMs:

Acetylated. Lysine acetylation by p300/EP300 is increased on high glucose conditions. Lysine acetylation promotes ubiquitination by UBR5. Acetylation is enhanced in the presence of BAG6. Deacetylated by SIRT2. Deacetylation of Lys-91 is carried out by SIRT1 and depends on PCK1 phosphorylation levels.

Phosphorylated in a GSK3B-mediated pathway; phosphorylation affects the efficiency of SIRT1-mediated deacetylation, and regulates PCK1 ubiquitination and degradation.

Ubiquitination by UBR5 leads to proteasomal degradation.
