How can the #ubiquitin #ligase APC/C recognize and inactivate the major kinase, CDK1-Cyclin B1, as soon as the spindle checkpoint is switched off?
Luca Cirillo, Rose Young et al identify chromosome as the key platform, recruiting both Cyclin B1 and APC3 via arginine anchor motifs in their sequences

How are specific dysfunctional #mitochondria removed under steady-state conditions?
Julia Pagan and coworkers (University of Queensland) show that an #SCF #ubiquitin #ligase based on #FBXL4, mutated in #MTDPS13, limits basal #mitophagy via #ubiquitination of #NIX and #BNIP3 receptors

What controls basal, #Parkin-independent #mitophagy?
E3 #ubiquitin #ligase screen by Sylvie Urbé, Michael Clague and coworkers identifies #VHL and #FBXL4 as negative regulators of mitophagy receptors #NIX and #BNIP3 via transcriptional and direct post-translational mechanisms, respectively
