Predicted to be involved in several processes, including endoplasmic reticulum to Golgi vesicle-mediated transport; organ growth; and positive regulation of secretion by cell. Predicted to act upstream of or within protein transport. Predicted to be located in endoplasmic reticulum and membrane. Predicted to be active in COPII-coated ER to Golgi transport vesicle; Golgi membrane; and endoplasmic reticulum membrane. Orthologous to human IER3IP1 (immediate early response 3 interacting protein 1).
