Structural and biophysical analysis of the proteasomal deubiquitinase, UCH37
… its C-terminal KEKE motif to the C-terminus of Rpn13, a proteasomal ubiquitin receptor which ensnares polyubiquitinated prey for degradation. UCH37 is known to be catalytically activated upon binding to Rpn13, allowing cleavage of Lys48-linked polyubiquitin chains from their distal end, an …

Polyubiquitin chain editing by UCH37 promotes degradation of a subset of proteasome substrates
Branched polyubiquitin can serve as a priority signal for proteasomal degradation by enhancing proteasomal degradation of modified substrates relative to substrates modified with homotypic K48-linked polyubiquitin chains. UCH37, a proteasome-associated deubiquitinating enzyme (DUB), has been shown …
