Coatomer protein complex, subunit zeta 2 encodes a subunit of the coatomer protein complex, a seven-subunit complex that functions in the formation of COPI-type, non-clathrin-coated vesicles. COPI vesicles function in the retrograde Golgi-to-ER transport of dilysine-tagged proteins. This gene is similar to a related family member, and the two encoded proteins form distinct isotypes of the coatomer protein complex. [provided by RefSeq]
