Although a previous study reported the crystal structure of the FBXO3 ApaG domain, how FBXO3 is incorporated into the SCF complex remains elusive. In the cryo-EM structure of SCF, the F-box domain of FBXO3 primarily associates with SKP1 via extensive hydrophobic interactions and interacts with the N-terminal region of CUL1 via hydrophobic interactions. The weak cryo-EM map of the RBX1 globular region is close to the FBXO3 ApaG domain, suggesting that unmodified SCF exhibits a closed conformation and that CUL1 neddylation is likely required to achieve high E3 activity. The structural study provides insight into the assembly of SCF and its activation mediated by CUL1 neddylation. | |||||||||
