Ubiquitinated proteins promote the association of proteasomes with the deubiquitinating enzyme Usp14 and the ubiquitin ligase Ube3c [Biochemistry]

In mammalian cells, the 26S proteasomes vary in composition. In addition to the standard 28 subunits in the 20S core particle and 19 subunits in each 19S regulatory particle, a small fraction (about 10–20% in our preparations) also contains the deubiquitinating enzyme Usp14/Ubp6, which regulates proteasome activity, and the ubiquitin...
