Cullin-based ubiquitin ligases: Cul3-BTB complexes join the family.
Cullin-based E3 ligases target substrates for ubiquitin-dependent degradation by the 26S proteasome. The SCF (Skp1-Cul1-F-box) and ECS (ElonginC-Cul2-SOCS box) complexes are so far the best-characterized cullin-based ligases. Their atomic structure has been solved recently, and several substrates have been described in different organisms. In addition to Cul1 and Cul2, higher eucaryotic genomes...
متن کاملVACM-1, a cullin gene family member, regulates cellular signaling.
Vasopressin-activated Ca(2+)-mobilizing (VACM-1) receptor binds arginine vasopressin (AVP) but does not have amino acid sequence homology with the traditional AVP receptors. VACM-1, however, is homologous with a newly discovered cullin family of proteins that has been implicated in the regulation of cell cycle through the ubiquitin-mediated degradation of cyclin-dependent kinase inhibitors. Bec...
متن کاملCullin Family Proteins and Tumorigenesis: Genetic Association and Molecular Mechanisms
Cullin family proteins function as scaffolds to form numerous E3 ubiquitin ligases with RING proteins, adaptor proteins and substrate recognition receptors. These E3 ligases further recognize numerous substrates to participate in a variety of cellular processes, such as DNA damage and repair, cell death and cell cycle progression. Clinically, cullin-associated E3 ligases have been identified to...
متن کاملStructure‐Guided Design of Peptides as Tools to Probe the Protein–Protein Interaction between Cullin‐2 and Elongin BC Substrate Adaptor in Cullin RING E3 Ubiquitin Ligases
Cullin RING E3 ubiquitin ligases (CRLs) are large dynamic multi-subunit complexes that control the fate of many proteins in cells. CRLs are attractive drug targets for the development of small-molecule inhibitors and chemical inducers of protein degradation. Herein we describe a structure-guided biophysical approach to probe the protein-protein interaction (PPI) between the Cullin-2 scaffold pr...
متن کاملCullin the Beef Cow Herd
Removing select cattle from a herd (culling) is done to improve herd performance and profitability Production and market conditions influence culling criteria Some cattle are obvious candidates for culling (e g , cows with poor breeding performance or cancer eye), but cattle can and should be culled for reasons that may not be readily observable Simply put, cows are selected for culling based o...
