| Primary Identifier | IPR040773 | Type | Domain |
| Short Name | Rpn6_N |
| description | This is the N-terminal domain found in Rpn6 proteins (26S proteasome regulatory subunit). 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 []. 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) []. Phosphorylation of Rpn6 enhances proteasome ATPase activity and promotes the formation of doubly capped (30S) proteasome, hence accelerating the degradation of short-lived proteins []. |
