COP I and COP II coat proteins direct protein and membrane trafficking in between early
compartments of the secretory pathway in eukaryotic cells. These coat proteins perform the
dual, essential tasks of selecting appropriate cargo proteins and deforming the lipid bilayer
of appropriate donor membranes into buds and vesicles. COP II proteins are required for
selective export of newly synthesized proteins from the endoplasmic reticulum (ER). COP I
proteins mediate a retrograde transport pathway that selectively recycles proteins from the …
COP I and COP II coat proteins direct protein and membrane trafficking in between early compartments of the secretory pathway in eukaryotic cells. These coat proteins perform the dual, essential tasks of selecting appropriate cargo proteins and deforming the lipid bilayer of appropriate donor membranes into buds and vesicles. COP II proteins are required for selective export of newly synthesized proteins from the endoplasmic reticulum (ER). COP I proteins mediate a retrograde transport pathway that selectively recycles proteins from the cis-Golgi complex to the ER. Additionally, COP I coat proteins have complex functions in intra-Golgi trafficking and in maintaining the normal structure of the mammalian interphase Golgi complex.
