abstractText | PUB domains are identified in several proteins functioning in the ubiquitin (Ub)-proteasome system and considered as p97-binding modules. To address the further functional roles of these domains, we herein characterized the interactions of the PUB domain of peptide:N-glycanase (PNGase) with Ub and Ub-like domain (UBL) of the proteasome shuttle factor HR23. NMR data indicated that PNGase-PUB exerts an acceptor preferentially for HR23-UBL, electrostatically interacting with the UBL surface employed for binding to other Ub/UBL motifs. Our findings imply that PNGase-PUB serves not only as p97-binding module but also as a possible activator of HR23 in endoplasmic reticulum-associated degradation mechanisms. |
