Essential for necroptosis, a programmed cell death process in response to death-inducing TNF-alpha family mbers. Upon induction of necrosis, RIPK3 interacts with, and phosphorylates RIPK1 and MLKL to form a necrosis-inducing complex. RIPK3 binds to and enhances the activity of three metabolic enzymes: GLUL, GLUD1, and PYGL. These metabolic enzymes may eventually stimulate the tricarboxylic acid cycle and oxidative phosphorylation, which could result in enhanced ROS production.
Mouse receptor interacting protein 3 does not contain a caspase-recruiting or a death domain but induces apoptosis and activates NF-kappaB.Pazdernik N.J., Donner D.B., Goebl M.G., Harrington M.A.Mol. Cell. Biol. 19:6500-6508(1999)
