C-terminal degron
WebA degron is defined as the minimal element within a protein that is sufficient for targeting the protein for UPS-mediated degradation in any structural environment. This means that degrons can be synthetically transferred to other proteins and still function as degradation signals (Ravid & Hochstrasser, 2008 ). WebDec 19, 2024 · The SsrA C-degron is particularly useful because its sequence can be easily identified within the tmRNA of different species. Since this degron is only functional when exposed at the C-terminus (Wei et al., 2011), all of the current targeted proteolysis systems are limited to C-terminal tagging. This may be problematic for some proteins if, for ...

WebDec 31, 2024 · Cereblon (CRBN) is a ubiquitously expressed E3 ligase substrate receptor and a key player in pharmaceutical targeted protein degradation. Despite substantial insight gained into its chemical ligand space that is exploited in small-molecule protein degraders, its cellular role and native mechanism of substrate recognition remained elusive so far. WebThe exposed N-terminal or C-terminal residues of proteins can act, in cognate sequence contexts, as degradation signals (degrons) that are targeted by specific E3 ubiquitin …
