Protein Structure
UniProt Annotation
Function Hydrolyzes glucose-6-phosphate to glucose in the endoplasmic reticulum. Forms with the glucose-6-phosphate transporter (SLC37A4/G6PT) the complex responsible for glucose production through glycogenolysis and gluconeogenesis. Hence, it is the key enzyme in homeostatic regulation of blood glucose levels.
Subcellular Localization Endoplasmic reticulum membrane; Multi-pass membrane protein.
Disease Associations Glycogen storage disease 1A (GSD1A) [MIM:232200]: A metabolic disorder characterized by impairment of terminal steps of glycogenolysis and gluconeogenesis. Patients manifest a wide range of clinical symptoms and biochemical abnormalities, including hypoglycemia, severe hepatomegaly due to excessive accumulation of glycogen, kidney enlargement, growth retardation, lactic acidemia, hyperlipidemia, and hyperuricemia. {ECO:0000269PubMed:10070617, ECO:0000269PubMed:10094563, ECO:0000269PubMed:10447271, ECO:0000269PubMed:10612834, ECO:0000269PubMed:10738005, ECO:0000269PubMed:10748407, ECO:0000269PubMed:10874313, ECO:0000269PubMed:10960498, ECO:0000269PubMed:11058903, ECO:0000269PubMed:11058910, ECO:0000269PubMed:12373566, ECO:0000269PubMed:15151508, ECO:0000269PubMed:15316959, ECO:0000269PubMed:15542400, ECO:0000269PubMed:7573034, ECO:0000269PubMed:7623438, ECO:0000269PubMed:7655466, ECO:0000269PubMed:8182131, ECO:0000269PubMed:8733042, ECO:0000269PubMed:9001800, ECO:0000269PubMed:9332655, ECO:0000269PubMed:9506659, ECO:0000269PubMed:9700612, ECO:0000269PubMed:9700613}.
