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       (By similarity). The zeta subunit may be involved in regulating the
CC       coat assembly and, hence, the rate of biosynthetic protein transport
CC       due to its association-dissociation properties with the coatomer
CC       complex (By similarity). {ECO:0000250|UniProtKB:P53600}.
CC   -!- SUBUNIT: Oligomeric complex that consists of at least the alpha, beta,
CC       beta', gamma, delta, epsilon and zeta subunits. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Golgi apparatus membrane
CC       {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic
CC       side {ECO:0000250}. Cytoplasmic vesicle, COPI-coated vesicle membrane
CC       {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic
CC       side {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the adaptor complexes small subunit family.
CC       {ECO:0000305}.
