Cand1 (Cullin-associated and neddylation-dissociated protein 1) has long been known as a regulator of SCF ubiquitin ligases, but details remained puzzling due to conflicting results from in vitro and in vivo experiments. Three recent reports, one in Cell and two in Nature Communications, propose Cand1 as a protein exchange factor with interesting mechanism that reconciles Cand1 genetics and biochemistry.
