Transportblåsor som bildas när cellhöljeklädda gropar fördjupas inåt och knoppas av. Det yttersta ytskiktet hos dessa vesikler är täckt med ett fackverksliknande nät av COP (coat protein complex)-proteiner, antingen COPI eller COPII. COPI-vesikler transporterar bakåt från Golgiapparatens hålrum till det grova endoplasmatiska nätverket, medan COPII-blåsor transporterar framåt från det grova endopla smatiska nätverket till Golgiapparaten.
TRANSPORT VESICLES formed when cell-membrane coated pits (COATED PITS, CELL-MEMBRANE) invaginate and pinch off. The outer surface of these vesicles is covered with a lattice-like network of COP (coat protein complex) proteins, either COPI or COPII. COPI coated vesicles transport backwards from the cisternae of the GOLGI APPARATUS to the rough endoplasmic reticulum (ENDOPLASMIC RETICULUM, ROUGH), while COPII coated vesicles transport forward from the rough endoplasmic reticulum to the Golgi apparatus.
