Cullin e3
WebJul 20, 2012 · Cullin E3 ligases are the largest family of ubiquitin ligases with diverse cellular functions. One of seven cullin proteins serves as a scaffold protein for the assembly of the multisubunit ubiquitin ligase complex. Cullin binds the RING domain protein Rbx1/Rbx2 via its C-terminus and a cullin-specific substrate adaptor protein via its N-terminus. WebCullin ring ubiquitin ligases are multi-subunit E3 ubiquitin ligases which use a specific cullin as a central scaffold to bridge an E2 enzyme to the substrate. All the cullin complexes use a cullin C-terminal portion to …

WebCullin neddylation has been reported to have a range of functional consequences for the activity of CRLs E3 ligases. First of all, CAND1 (Cullin-associated and neddylation-dissociated-1), a large sequestration factor, binds to unmodified cullin, leading to inhibition of the binding of the substrate receptor-adaptor module to the N-terminus. WebCullin 3 (CUL3) is the scaffold of Cullin3 Ring E3-ligases (CRL3s), which use various BTB-adaptor proteins to ubiquitinate numerous substrates targeting their proteasomal degradation. CUL3 mutations, responsible for a severe form of familial hyperkalemia and hypertension (FHHt), all result in a deletion of exon 9 (amino-acids 403-459) (CUL3-∆9).
WebThe cullin-really interesting new gene (RING) ligase, comprising more than 200 different members, constitutes the largest subfamily of human E3 ubiquitin ligases [35,36,37]. To test the hypothesis that cullin RING ligases may regulate ClC-2 protein expression, we employed a potent inhibitor of cullin RING E3 ligases, MLN4924 [38,39]. WebCullin-5 is a protein that in humans is encoded by the CUL5 gene. ... Cul5 inhibits cellular proliferation, potentially through its involvement in the SOCS/ BC-box/ eloBC/ cul5/ RING E3 ligase complex, which functions as part of the ubiquitin system for protein degradation.
