'''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>.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
