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 act upstream of or within protein transport and vesicle-mediated transport. Located in perinuclear region of cytoplasm. 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). [provided by Alliance of Genome Resources, Apr 2022]
