Abstract
This is the C-terminal domain found in RPN1 proteins (26S proteasome non-ATPase regulatory subunit 2). The 26S proteasome holocomplex consists of a 28-subunit barrel-shaped core particle (CP) in the centre capped at the top and bottom by 19-subunit regulatory particles (RPs). The CP forms the catalytic chamber and the RP is formed from two subcomplexes known as the lid and the base [ 1 ]. The lid comprises nine Rpn subunits in yeast (Rpn3/5/6/7/8/9/11/12/15) and the base comprises three Rpn subunits (Rpn1/2/13) and six ATPases (Rpt1-6) [ 2 ].
