Mutual inactivation of two RING-finger-type E3 ubiquitin ligases during cell cycle progression

open access: yesMolecular & Cellular Oncology, 2021
CRL and APC/C belong to the RING-finger-type E3 ligases, and both play important roles in cell cycle regulation. Recently, we found that SAG, a RING component of CRL, acts as an endogenous inhibitor of APC/C by competing with APC2 for E2s binding; while ...
