Sar1a - secretion associated, Ras related GTPase 1A

Predicted to enable inorganic diphosphatase activity and magnesium ion binding activity. Predicted to be involved in COPII-coated vesicle cargo loading and phosphate-containing compound metabolic process. Predicted to act upstream of or within negative regulation of cargo loading into COPII-coated vesicle and vesicle-mediated transport. Predicted to be located in Golgi apparatus and sarcoplasmic reticulum. Predicted to be part of COPII vesicle coat. Predicted to be active in cytosol. Orthologous to human SAR1A (secretion associated Ras related GTPase 1A). [provided by Alliance of Genome Resources, Apr 2022]
