Protein attributes

Sequence length	346 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Hydrolyzes glucose-6-phosphate to glucose in the endoplasmic reticulum. May form with the glucose-6-phosphate transporter (SLC37A4/G6PT) a ubiquitously expressed complex responsible for glucose production through glycogenolysis and gluconeogenesis. Probably required for normal neutrophil function By similarity.
Catalytic activity	D-glucose 6-phosphate + H2O = D-glucose + phosphate.
Enzyme regulation	Inhibited by vanadate By similarity.
Pathway	Carbohydrate biosynthesis; gluconeogenesis.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.
Sequence similarities	Belongs to the glucose-6-phosphatase family.
