MLKL was phosphorylated by RIP3 at the serine 358 and threonine 357 residues, which induces a conformational change into its active state [25], and then formed tetramers and translocated onto the plasma membrane, which injures cellular membrane integrity resulting in cell swelling and membrane rupture [26].
Excessive ROS production mediated by the necrosome occurs through the following mechanisms: (a) RIP3 can allosterically activate glutamate-ammonia ligase or glutamine synthetase (GLUL) and glutamate dehydrogenase (GLUD1) enzymes.

In order to assess whether PPAR-[gamma] activation also inhibits inflammation-induced necroptosis, expressions of RIP1, RIP3, and MLKL, the three critical components of necroptosis [29], were evaluated in the myocardium.

However, several lines of evidence demonstrate that prolonged and excessive activation of TAK1 induces phosphorylation and activation of RIP3, leading to necroptosis even without TNF stimulation, whereas ablation of TAK1 causes caspase-dependent apoptosis (25).
Necroptosis has been shown to be generally dependent on RIP3, which is activated following phosphorylation by the serine/threonine kinase RIP1 [13].
