General annotation (Comments)

Function

The coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin-coated vesicles, which further mediate biosynthetic protein transport from the ER, via the Golgi up to the trans Golgi network. Coatomer complex is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins. Ref.8

Subunit structure

Oligomeric complex that consists of at least the alpha, beta, beta', gamma, delta, epsilon and zeta subunits. Interacts with the ESCRT-0 subunit VPS27. Ref.8

Subcellular location

Cytoplasm By similarity. Golgi apparatus membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Cytoplasmic vesicle › COPI-coated vesicle membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Note: The coatomer is cytoplasmic or polymerized on the cytoplasmic side of the Golgi, as well as on the vesicles/buds originating from it By similarity. Ref.6 Ref.8

Miscellaneous

Present with 129000 molecules/cell in log phase SD medium.

Sequence similarities

Belongs to the WD repeat COPB2 family.

Contains 6 WD repeats.
