WebJan 24, 2001 · The E3 ubiquitin-protein ligase activity of the complex is dependent on the neddylation of the cullin subunit and is inhibited by the association of the deneddylated cullin subunit with TIP120A/CAND1. The functional specificity of the BCR complex depends on the BTB domain-containing protein as the substrate recognition component. WebJan 5, 2000 · The F-box is a protein motif of approximately 50 amino acids that functions as a site of protein-protein interaction. F-box proteins were first characterized as components of SCF ubiquitin-ligase complexes (named after their main components, Skp I, Cullin, and an F-box protein), in which they bind substrates for ubiquitin-mediated proteolysis.
The Biology of F-box Proteins: The SCF Family of E3 …
WebThe evolutionarily conserved cullin family proteins can assemble as many as >600 distinct E3 ubiquitin ligase complexes that regulate diverse cellular pathways. In most of Cullin-RING ubiquitin ligase (CRL) complexes, separate linker and adaptor proteins build the substrate recognition module. Differently, a single BTB-containing adaptor ... WebMar 20, 2013 · Among all E3 ubiquitin ligases, the SCF (SKP1-CUL1-F-box protein) E3 ligases are the largest family and are responsible for the turnover of many key regulatory proteins. Aberrant regulation of SCF E3 ligases is associated with various human diseases, such as cancers, including skin cancer. ... Cullin Proteins / metabolism* how are site and situation related
