Predicted to enable GTPase activator activity. Predicted to be involved in COPII-coated vesicle cargo loading. Located in endoplasmic reticulum exit site. Expressed in hypodermis. Human ortholog(s) of this gene implicated in Cowden syndrome 7; congenital dyserythropoietic anemia type II; and craniolenticulosutural dysplasia. Is an ortholog of human SEC23B (SEC23 homolog B, COPII coat complex component).
Predicted to be located in extracellular space. Is an ortholog of human CLEC18A (C-type lectin domain family 18 member A); CLEC18B (C-type lectin domain family 18 member B); and CLEC18C (C-type lectin domain family 18 member C).
