domain:Rich in dileucine repeats, which have been implicated in trafficking of a variety of transmembrane proteins.,function:Belongs to the 26S multisubunit protease, which is required for ubiquitin-dependent proteolysis. Does not bind ubiquitin polymers.,similarity:Belongs to the proteasome subunit S5B family.,subunit:26S protease is composed of a multicatalytic protease (proteasome) and a regulatory ATPase complex. Both are multisubunit structures that associate in the presence of ATP to form the protease. Subunit S5B is part of the regulatory complex.,
