'''Coatomers''' (COPI) are a set of vesicles' coating proteins <ref>PMID:1898986</ref>. Coatomers contain several subunits which are named according to decreasing molecular weight as alpha, beta', gamma, delta, epsilon and zeta-1. Protein ADP-ribosylation factor 1 (Arf-1) is part of the vesicle-coating complex<ref>PMID:9681627</ref>. | '''Coatomers''' (COPI) are a set of vesicles' coating proteins <ref>PMID:1898986</ref>.
