Scaffolding protein RAPSYN can exert its NEDD8 E3 ligase activity to neddylate and stabilize oncogenic BCR-ABL by competing proteasomal degradation in Ph+ leukemia.

Direct measurements of trafficking kinetics between organelles of the secretory pathway suggest that lipid-driven membrane domains laterally sort proteins during membrane traffic.
The autophagosomal membrane becomes negatively charged during maturation due to the accumulation of PI4P, leading to the recruitment of syntaxin 17, which is required for autophagosome-lysosome fusion.
A change in the electric charge of autophagosome membranes controls the recruitment of SNARE proteins to ensure that membrane fusion occurs at the right time during autophagy.
