Conformational switching of the pseudokinase domain promotes human MLKL tetramerization and cell death by necroptosis

RIPK3-mediated phosphorylation of the mixed lineage kinase domain-like (MLKL) pseudokinase is thought to be the trigger for MLKL activation during necroptotic signaling. Here the authors provide evidence that the transition of human MLKL from a monomeric state to a tetramer is essential for necroptosis signalling.
