function:Component of the COPII coat, that covers ER-derived vesicles involved in transport from the endoplasmic reticulum to the Golgi apparatus. COPII acts in the cytoplasm to promote the transport of secretory, plasma membrane, and vacuolar proteins from the endoplasmic reticulum to the Golgi complex.,similarity:Belongs to the SEC23/SEC24 family. SEC23 subfamily.,subunit:COPII is composed of at least five proteins: the Sec23/24 complex, the Sec13/31 complex and Sar1.,
Cytoplasmic vesicle, COPII-coated vesicle membrane ; Peripheral membrane protein ; Cytoplasmic side . Endoplasmic reticulum membrane ; Peripheral membrane protein ; Cytoplasmic side . Cytoplasm, cytosol .
