Predicted to enable SNARE binding activity and zinc ion binding activity. Predicted to be involved in COPII-coated vesicle cargo loading. Predicted to act upstream of or within several processes, including animal organ development; artery morphogenesis; and regulation of cargo loading into COPII-coated vesicle. Located in COPII-coated ER to Golgi transport vesicle. Orthologous to human SEC24B (SEC24 homolog B, COPII coat complex component). [provided by Alliance of Genome Resources, Apr 2022]
