spinqualitylabelsall models Human COP9 signalosome subunits 1 (grey and wheat), 2 (green and blue), 3 (pink and rust), 4 (yellow and aqua), 5 (magenta and olive), 6 (cyan and orchid), 7A (gold and turquoise), 8 (red and neon green) (PDB code 4d10) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image COP9 (COnstitutive Photomorphogenesis 9) signalosome catalyzes the hydrolysis of NEDD8 protein from the cullin subunit of cullin-ring ubiquitin ligase. COP9 functions in the ubiquitin-proteasome pathway. COP9 contains 8 subunits and is homologous to the lid of the 26S proteasome[1].
