Cullins are a family of hydrophobic scaffold proteins which provide support for ubiquitin ligases (E3). All eukaryotes appear to have cullins. They combine with RING proteins to form Cullin-RING ubiquitin ligases (CRLs) that are highly diverse and play a role in myriad cellular processes, most notably protein … See more Cullin-RING ubiquitin ligases (CRLs), such as Cul1 (SCF) play an essential role in targeting proteins for ubiquitin-mediated destruction; as such, they are diverse in terms of composition and function, regulating many … See more With the exception of ANAPC2, each member of the cullin family is modified by Nedd8 and several cullins function in Ubiquitin-dependent proteolysis, a process in which the 26S See more • Cullin family - Sanger Institute website. • Cullin+Proteins at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more WebMar 10, 2024 · Since both p21 and p27 are well-defined substrates for CRL1- and CRL4-based ubiquitin ligases, it is tempting to speculate that at least some degree of IP6's anticancer activity might come from increased down-regulation of CRL function, thus stabilizing p21 and p27 to promote G1 arrest.

WebAbstract: Cullin-RING E3 ligases (CRLs) are the largest family of E3 ubiquitin ligases, responsible for about 20% of the protein degradation by the ubiquitin-proteasome system (UPS). Given their vital roles in multiple cellular processes, and over-activation in many human cancers, CRLs are validated as promising targets for anti-cancer therapies. WebApr 12, 2024 · The damaged DNA-binding protein 1 (DDB1) enhances the survival and maintenance of multipotent cells through promoting the Cullin 4 E3 ligase complex-dependent ubiquitination and subsequent degradation of downstream substrates. Naive T cells could be activated and differentiated into effector and memory T cells by exogenous … WebHere, we summarize the versatile roles of the CRL4 E3 ligase complexes in tumorigenesis dependent on the evidence obtained from knockout and transgenic mouse models as well as biochemical and pathological studies.
