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. WebOct 1, 2024 · Upon binding, CSN and neddylated Cullin undergo conformational changes, and the N-terminal domains of CSN2 and CSN4 as well as the RING domain of Rbx1 enable the formation of a highly active complex that is stabilized by CSN5 interactions with the neddylated Cullin [37 ].
