General Information of Binding Target of SBP (BTS) (ID: ST00207)
BTS Name
Mixed lineage kinase domain-like protein
Synonyms
hMLKL
BTS Type
Protein
Family
Protein kinase superfamily
Gene Name
MLKL
Organism
Homo sapiens (Human)
Function
Pseudokinase that plays a key role in TNF-induced necroptosis, a programmed cell death process Does not have protein kinase activity 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 In addition to TNF-induced necroptosis, necroptosis can also take place in the nucleus in response to orthomyxoviruses infection: following activation by ZBP1, MLKL is phosphorylated by RIPK3 in the nucleus, triggering disruption of the nuclear envelope and leakage of cellular DNA into the cytosol.following ZBP1 activation, which senses double-stranded Z-RNA structures, nuclear RIPK3 catalyzes phosphorylation and activation of MLKL, promoting disruption of the nuclear envelope and leakage of cellular DNA into the cytosol (By similarity). Binds to highly phosphorylated inositol phosphates such as inositolhexakisphosphate (InsP6) which is essential for its necroptotic function
