背景 | Of the subunits that comprise the 19S RP lid, only PSMD14 (POH1) has a known function. PSMD14 is classified as a metalloenzyme DUB and its activity has been shown to be critical for proteasome function in both yeast and humans (3-6). Indeed, PSMD14 harbors an Mpr1-Pad1-N-terminal (MPN) domain with an embedded, highly conserved signature motif for metal-dependent isopeptidases that has been dubbed JAMM, from Jab1/Pad1/MPN domain metalloenzyme. The JAMM motif of PSMD14 consists of a pattern of four charged amino acids: a glutamate residue followed by two histidines and an aspartate (EXnHXHX10D). It has been proposed that the histidine residues, in concert with the aspartate, bind to a zinc ion that, together with the preceding glutamate, forms the catalytic site of PSMD14 (3,4). PSMD14 is thought to cleave ubiquitin chains with proximal specificity relative to the substrate, thus removing whole ubiquitin chains en bloc (3). Recent studies have implicated PSMD14 as an important regulator of ErbB2 (7) and c-Jun (8) protein levels. |
