Predicted to enable GTPase activator activity and zinc ion binding activity. Involved in protein localization to plasma membrane. Located in COPII-coated ER to Golgi transport vesicle; Golgi membrane; and perinuclear region of cytoplasm. Is expressed in central nervous system; craniocervical region bone; retina; and thoracic segment skeleton. Human ortholog(s) of this gene implicated in craniolenticulosutural dysplasia. Orthologous to human SEC23A (SEC23 homolog A, COPII coat complex component). [provided by Alliance of Genome Resources, Apr 2022]
