Disease
G6PC1_HUMAN Glycogen storage disease due to glucose-6-phosphatase deficiency type Ia. The disease is caused by variants affecting the gene represented in this entry.
Function
G6PC1_HUMAN 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 in the terminal step of glycogenolysis and gluconeogenesis. Hence, it is the key enzyme in homeostatic regulation of blood glucose levels.[1] [2] [3] [4] [5]
