Predicted to be involved in Golgi organization; endoplasmic reticulum to Golgi vesicle-mediated transport; and intracellular protein transport. Predicted to act upstream of or within protein transport. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. Predicted to be active in several cellular components, including COPII-coated ER to Golgi transport vesicle; Golgi apparatus; and endoplasmic reticulum-Golgi intermediate compartment. Orthologous to human TMED1 (transmembrane p24 trafficking protein 1). [provided by Alliance of Genome Resources, Apr 2022]
