Sec23b - Sec23 homolog B, COPII coat complex component

Predicted to enable GTPase activator activity. Predicted to be involved in COPII-coated vesicle cargo loading. Predicted to be located in endoplasmic reticulum and perinuclear region of cytoplasm. Predicted to be part of COPII vesicle coat. Predicted to be active in endoplasmic reticulum exit site. Human ortholog(s) of this gene implicated in Cowden syndrome 7 and congenital dyserythropoietic anemia type II. Orthologous to human SEC23B (SEC23 homolog B, COPII coat complex component).
