basic FUNCTION
  • main control point for the regulation of gluconeogenesis
  • catalyzing the formation of phosphoenolpyruvate from oxaloacetate, with the release of carbon dioxide and GDP
  • functions in the pathway for the conversion of gluconeogenic precursors to glucose and contributes to glycerol-3-phosphate synthesis through glyceroneogenesis
  • PCK1 plays an important role in both the mammary gland adipocytes and epithelial cells during lactation
  • acid-induced PCK1 provides glucose for acid-base homeostasis at an individual level, which is supported by rapid pumping of H(+) via V-ATPase at the cellular level
  • PCK1 plays a regulatory role in gluconeogenesis and glyceroneogenesis
  • PCK1 activity contributes to metabolic reprogramming and polarization in macrophages
  • importance of the protein kinase activity of PCK1 in the activation of SREBPs, lipogenesis and the development of hepatocellular carcinoma (HCC)

    GTP
    protein
  • PCK1 is acetylated by the EP300 acetyltransferase, and this acetylation stimulates the interaction between PCK1 and UBR5, a HECT domain containing E3 ubiquitin ligase, therefore promoting PCK1 ubiquitinylation and degradation
  • overexpression of ESRRG induced PCK1 and G6PC gene expression and glucose production in primary hepatocytes
  • thyroid hormone (TH), a regulator of hepatic gluconeogenesis acts through its nuclear receptor (THRA, THRB) to induce the expression of PCK1 and G6PC
  • mechanistically, LAMTOR5 inhibited the expression of PCK1 through down-regulating transcription factor FOXO1 in hepatoma cells
  • CREB3L3 regulates the rhythmic expression of the genes encoding the rate-limiting enzymes for glycogenolysis and gluconeogenesis, including PYGL, PCK1, and G6PC
  • PCK1 reduces the stability of LDHA through posttranslational regulation and the effects of PCK1 on glucose metabolism, cell proliferation and metastasis are mediated via the inhibition of LDHA
  • gluconeogenic enzyme PCK1 phosphorylates INSIG1/INSIG2 for lipogenesis
  • cell & other
