Comments
  • FUNCTION: May hydrolyze glucose-6-phosphate to glucose in the endoplasmic reticulum. May be responsible for glucose production through glycogenolysis and gluconeogenesis (By similarity).
  • CATALYTIC ACTIVITY: D-glucose 6-phosphate + H2O = D-glucose + phosphate.
  • PATHWAY: Carbohydrate biosynthesis; gluconeogenesis.
  • SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass membrane protein (By similarity).
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing.
    Name1
    Isoform IDQ9Z186-1
    This is the isoform sequence displayed in this entry.
    Name2
    Isoform IDQ9Z186-2
    Features which should be applied to build the isoform sequence: VSP_033650, VSP_033651.
  • TISSUE SPECIFICITY: Specifically expressed in pancreatic islet cells, in particular those of beta-cell origin. Not detected in testis, kidney, muscle, liver, lung, spleen, brain, pituitary, gastric fundus or heart.
  • DEVELOPMENTAL STAGE: Initial onset of expression in the pancreas is at E12 and prominent expression is detected at E14.
  • INDUCTION: Up-regulated in islet cells cultured in hyperglycemic concentrations of glucose.
  • PTM: N-glycosylated; the non-glycosylated form is more unstable and is degraded through the proteasome (By similarity).
  • MISCELLANEOUS: Mice lacking G6pc2 are no overt anatomical or behavioral phenotype but display a mild metabolic phenotype. Upon fasting those mice exhibit a significant decrease in blood glucose and triacylglycerol compared to wild type mice.
  • MISCELLANEOUS: G6pc2 is an autoantigen which is the natural target of a prevalent T-cell population causing insulin-dependent diabetes mellitus through destruction of pancreatic beta cells.
  • SIMILARITY: Belongs to the glucose-6-phosphatase family.
  • SEQUENCE CAUTION:
    • Sequence=AAI11906.1; Type=Erroneous translation; Note=Wrong choice of CDS
