Cullin neddylation
WebJun 21, 2024 · UBE2M and UBE2F are two family members of neddylation E2 conjugating enzyme that, together with E3s, activate CRLs (Cullin-RING Ligases) by catalyzing cullin neddylation. However, whether and how two E2s cross-talk with each other are largely unknown. Here, we report that UBE2M is a stress-inducible … WebAug 1, 2006 · Neddylation is inhibited by the tight binding of cullins to CAND1 (cullin-associated and neddylation-dissociated 1) protein, and Nedd8 is removed from cullins by specific isopeptidase activity of the COP9/signalosome (CSN) complex. The mechanisms that regulate neddylation and deneddylation of cullins were unknown.

WebMar 1, 2024 · Neddylation, the conjugation of a Ub-like protein NEDD8 to a target protein such as the cullin, represents a key regulatory mechanism for CRLs. Biochemical and structural studies of a few CRLs have revealed that cullin neddylation alters the CRL conformation and activates CRL-dependent protein ubiquitination. Here, using CUL2 … WebThe primary known substrates of NEDD8 modification are the cullin subunits of cullin-based E3 ubiquitin ligases, which are active only when NEDDylated. Their NEDDylation is critical for the recruitment of E2 to the ligase complex, thus facilitating ubiquitin conjugation.
WebMar 17, 2024 · Cullin neddylation is required for activation of CRLs [ 43 ], and accumulated data have shown that CRLs are actively involved in regulation of morphology, trafficking, functions, and the degradation of mitochondria (Table 1 and Fig. 2 ).

To further exclude the possible regulation of cullin E3 ligase on SETD7, we then used MLN4924 to treat HEK293T cells, and the results were consistent with the conclusion that CRL4A DDB1 E3 ligase complex did not regulate SETD7 (Fig. 2B, C). We then knocked down DDB1 in HEK293T … WebGiven that cullin neddylation is required for CRL activity, and CRLs control the turn-over of a variety of key signal proteins and are often abnormally activated in cancers, targeting …
