WebCullins are modified by NEDD8, a ubiquitin-like protein. This process, referred to as neddylation, promotes the E3 activity of CRLs by inducing conformational rearrangement in the Cullin-RING catalytic core. Cand1 is a cullin-associated protein whose binding is excluded by cullin neddylation. WebApr 19, 2024 · BTB-Kelch proteins are substrate-specific adaptors for cullin-3 (Cul3) RING-box-based E3 ubiquitin ligases, mediating protein ubiquitylation for subsequent proteasomal degradation. Vaccinia virus encodes three BTB-Kelch proteins: A55, C2, and F3. Viruses lacking A55 or C2 have altered cytopathic effects in cultured cells and altered pathology ...
