<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

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:22265413, PubMed:22265414, PubMed:22421439, PubMed:24316671). Binds to highly phosphorylated inositol phosphates such as inositolhexakisphosphate (InsP6) which is essential for its necroptotic function (PubMed:29883610).5 Publications

Miscellaneous

Interaction with RIPK3 is species specific: human MLKL only interacts with human RIPK3 and not mouse RIPK3.1 Publication

<p>This subsection of the <a href="http://www.uniprot.org/help/function%5Fsection">Function</a> section describes regulatory mechanisms for enzymes, transporters or microbial transcription factors, and reports the components which regulate (by activation or inhibition) the reaction.<p><a href='/help/activity_regulation' target='_top'>More...</a></p>Activity regulationi

Activated via binding to highly phosphorylated inositol phosphates such as inositolhexakisphosphate (InsP6) which mediates the release of an N-terminal auto-inhibitory region. Activation requires not only RIPK3-dependent phosphorylation but also binding to highly phosphorylated inositol phosphates (PubMed:29883610). Inhibited by necrosulfonamide, a specific inhibitor of necroptosis that targets Cys-86.2 Publications

Homooligomer (PubMed:29883610). Homotrimer; forms homotrimers on necroptosis induction.

Interacts with RIPK3; the interaction is direct. 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.
