Predicted to enable GTPase activity. Involved in embryo development. Predicted to be located in endoplasmic reticulum exit site. Predicted to be part of COPII vesicle coat. Human ortholog(s) of this gene implicated in chylomicron retention disease. Is an ortholog of human SAR1A (secretion associated Ras related GTPase 1A) and SAR1B (secretion associated Ras related GTPase 1B).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
