Predicted to enable SNAP receptor activity and SNARE binding activity. Involved in lumen formation, open tracheal system. Predicted to be part of SNARE complex. Predicted to be active in Golgi apparatus; cytoplasmic vesicle membrane; and endoplasmic reticulum membrane. Is expressed in adult head. Used to study progressive myoclonus epilepsy. Human ortholog(s) of this gene implicated in progressive myoclonus epilepsy 6. Orthologous to human GOSR2 (golgi SNAP receptor complex member 2).
