CC -!- FUNCTION: The coatomer is a cytosolic protein complex that binds to
CC dilysine motifs and reversibly associates with Golgi non-clathrin-
CC coated vesicles, which further mediate biosynthetic protein transport
CC from the ER, via the Golgi up to the trans Golgi network. Coatomer
CC complex is required for budding from Golgi membranes, and is essential
CC for the retrograde Golgi-to-ER transport of dilysine-tagged proteins.
CC {ECO:0000256|PIRNR:PIRNR005727}.
CC -!- SUBUNIT: Oligomeric complex that consists of at least the alpha, beta,
CC beta', gamma, delta, epsilon and zeta subunits.
