Role and mechanism of mixed lineage kinase domain-like protein in cerebral ischemia / 国际脑血管病杂志

ABSTRACT

Mixed lineage kinase domain-like protein (MLKL) is a pseudokinase with a kinase domain, which plays an important role in the regulation of necroptosis. After cerebral ischemia, MLKL, as the substrate protein of the receptor-interacting protein 3, undergoes oligomerization and phosphorylation, and then translocates from the cytoplasm to the plasmalemma, causing mitochondrial division and cell membrane rupture. MLKL can also mediate the inflammatory response after cerebral ischemia by inducing necroptosis and directly activating inflammasomes, thereby aggravating brain injury. Therefore, to clarify the biological characteristics of MLKL and its role and mechanism in cerebral ischemia is very important for the treatment of cerebral ischemia.
