Function
Cytosolic phosphoenolpyruvate carboxykinase that catalyzes the reversible decarboxylation and phosphorylation of oxaloacetate (OAA) and acts as the rate-limiting enzyme in gluconeogenesis (PubMed:24863970, PubMed:26971250, PubMed:28216384, PubMed:30193097). Regulates cataplerosis and anaplerosis, the processes that control the levels of metabolic intermediates in the citric acid cycle (PubMed:24863970, PubMed:26971250, PubMed:28216384, PubMed:30193097). At low glucose levels, it catalyzes the cataplerotic conversion of oxaloacetate 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 (PubMed:30193097). At high glucose levels, it catalyzes the anaplerotic conversion of phosphoenolpyruvate to oxaloacetate (PubMed:30193097). Acts as a regulator of formation and maintenance of memory CD8(+) T-cells: up-regulated in these cells, where it generates phosphoenolpyruvate, via gluconeogenesis (By similarity). The resultant phosphoenolpyruvate flows to glycogen and pentose phosphate pathway, which is essential for memory CD8(+) T-cells homeostasis (By similarity). In addition to the phosphoenolpyruvate carboxykinase activity, also acts as a protein kinase when phosphorylated at Ser-90: phosphorylation at Ser-90 by AKT1 reduces the binding affinity to oxaloacetate and promotes an atypical serine protein kinase activity using GTP as donor (PubMed:32322062). The protein kinase activity regulates lipogenesis: upon phosphorylation at Ser-90, translocates to the endoplasmic reticulum and catalyzes phosphorylation of INSIG proteins (INSIG1 and INSIG2), thereby disrupting the interaction between INSIG proteins and SCAP and promoting nuclear translocation of SREBP proteins (SREBF1/SREBP1 or SREBF2/SREBP2) and subsequent transcription of downstream lipogenesis-related genes (PubMed:32322062).

Supplementary info

- Activity summary
The protein PCK1 also known as phosphoenolpyruvate carboxykinase PEPC or PEPCK plays an important role in gluconeogenesis by converting oxaloacetate to phosphoenolpyruvate (PEP). It has a molecular mass of around 69 kDa. PCK1 is primarily expressed in the liver kidney and adipose tissues. Through its enzymatic activity PCK1 helps to regulate blood glucose levels allowing for the production of glucose from non-carbohydrate sources.
- Biological function summary
PCK1 is essential for maintaining glucose homeostasis in the body. Although not part of a larger protein complex its function directly impacts the tricarboxylic acid (TCA) cycle by providing substrates for glucose synthesis. By orchestrating the conversion of oxaloacetate to PEP PCK1 contributes significantly to reducing dependency on dietary carbohydrates particularly during fasting or intensive physical activity.
- Pathways
PCK1 integrates critical metabolic processes. It mainly influences the gluconeogenesis and glycolysis pathways. In the gluconeogenesis pathway PCK1 coordinates with enzymes such as glucose-6-phosphatase to facilitate the generation of glucose from lactate and amino acids. Additionally its role in glycolysis intersects with enzymes like pyruvate kinase managing energy production and consumption.
- Associated diseases and disorders
PCK1 links to conditions such as diabetes mellitus and metabolic syndrome. Altered expression or function of PCK1 can lead to disturbances in glucose metabolism. In diabetes dysregulation of PCK1 expression can contribute to hyperglycemia. Additionally PCK1 and its interaction with insulin signaling pathways is critical as insulin resistance is an important feature of metabolic syndrome. Understanding these connections offers potential avenues for therapeutic intervention in metabolic diseases.

We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody.
Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.
