Mlkl, Mixed lineage kinase domain-like protein
Also Known as
Pseudokinase that plays a key role in TNF-induced necroptosis, a programmed cell death process. Activated following phosphorylation by RIPK3, leading to homotrimerization, localization to the plasma membrane and execution of programmed necrosis characterized by calcium influx and plasma membrane damage. Does not have protein kinase activity (PubMed:23835476, PubMed:24012422, PubMed:24019532). Binds to highly phosphorylated inositol phosphates such as inositolhexakisphosphate (InsP6) which is essential for its necroptotic function. Homooligomer (By similarity). Homotrimer; forms homotrimers on necroptosis induction. Upon TNF-induced necrosis, forms in complex with PGAM5, RIPK1 and RIPK3. Within this complex, may play a role in the proper targeting of RIPK1/RIPK3 to its downstream effector PGAM5 (By similarity). Interacts with RIPK3; the interaction is direct.
