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 In mammals, the coatomer can only be recruited by membranes associated
CC to ADP-ribosylation factors (ARFs), which are small GTP-binding
CC proteins; the complex also influences the Golgi structural integrity,
CC as well as the processing, activity, and endocytic recycling of LDL
CC receptors (By similarity). {ECO:0000250}.
CC -!- FUNCTION: This coatomer complex protein, essential for Golgi budding
CC and vesicular trafficking, is a selective binding protein (RACK) for
CC protein kinase C, epsilon type. It binds to Golgi membranes in a GTP-
CC dependent manner (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Oligomeric complex that consists of at least the alpha, beta,
CC beta', gamma, delta, epsilon and zeta subunits. Probably interacts with
CC PEX11A. Interacts with SCYL1. Interacts with JAGN1 (By similarity).
CC {ECO:0000250, ECO:0000250|UniProtKB:P35606}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000250}. Golgi apparatus
CC membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250};
CC Cytoplasmic side {ECO:0000250}. Cytoplasmic vesicle, COPI-coated
CC vesicle membrane {ECO:0000250}; Peripheral membrane protein
CC {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=The coatomer is
CC cytoplasmic or polymerized on the cytoplasmic side of the Golgi, as
CC well as on the vesicles/buds originating from it. Shows only a slight
CC preference for the cis-Golgi apparatus, compared with the trans-Golgi.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the WD repeat COPB2 family. {ECO:0000305}.
