== Publication Abstract from PubMed == | |||
Proteome integrity depends on the ubiquitin-proteasome system to degrade unwanted or abnormal proteins. In addition to the N-degrons, C-terminal residues of proteins can also serve as degradation signals (C-degrons) that are recognized by specific cullin-RING ubiquitin ligases (CRLs) for proteasomal degradation. FEM1C is a CRL2 substrate receptor that targets the C-terminal arginine degron (Arg/C-degron), but the molecular mechanism of substrate recognition remains largely elusive. Here, we present crystal structures of FEM1C in complex with Arg/C-degron and show that FEM1C utilizes a semi-open binding pocket to capture the C-terminal arginine and that the extreme C-terminal arginine is the major structural determinant in recognition by FEM1C. Together with biochemical and mutagenesis studies, we provide a framework for understanding molecular recognition of the Arg/C-degron by the FEM family of proteins. | |||
