Coatomer subunit epsilon is a protein that in humans is encoded by the COPE gene.^[5]^[6]

Function

The product of this gene is an epsilon subunit of coatomer protein complex. Coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin-coated vesicles. It is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins. Coatomer complex consists of at least the alpha, beta, beta', gamma, delta, epsilon and zeta subunits. Alternatively spliced transcript variants encoding different isoforms have been identified.^[6]

Interactions

COPE (gene) has been shown to interact with COPA.^[7]^[8]^[9]
