Predicted to be involved in endoplasmic reticulum to Golgi vesicle-mediated transport; regulation of ER to Golgi vesicle-mediated transport; and vesicle fusion with Golgi apparatus. Predicted to be located in several cellular components, including COPII-coated ER to Golgi transport vesicle; Golgi apparatus; and endoplasmic reticulum exit site. Predicted to be active in trans-Golgi network. Orthologous to human YIPF5 (Yip1 domain family member 5). [provided by Alliance of Genome Resources, Apr 2022]
