Definition

The membrane surrounding a COPI-coated vesicle. COPI-coated vesicles mediate the vesicular transport of cargo such as proteins. COPI-coated vesicles are believed to bud from the cis-cisternae of the Golgi apparatus, mediate traffic from the cis-Golgi back to the ER (retrograde), and govern the flow pattern of materials within the Golgi stack. COPI is composed of the coatomer, which is a seven-subunit protein complex that participates in the formation of Golgi-derived coated vesicles. Evidence has also been presented for anterograde intra-Golgi transport mediated by COPI in yeast and mammals.
