The pseudokinase mixed lineage kinase domain-like (MLKL), is the terminal known obligatory effector in the necroptosis pathway, and is activated following phosphorylation by receptor interacting protein kinase-3 (RIPK3). Activated MLKL translocates to membranes, leading to membrane destabilisation and subsequent cell death. Heat‑shock protein 90 (HSP90) and cell division cycle 37 (CDC37) cochaperone complex contributes to activation of MLKL (Jacobsen AV et al. 2016; Zhao XM et al. 2016; Bigenzahn JW et al. 2016). Whether HSP90 exerts its effects on MLKL folding, oligomerization, or translocation to membranes has not been precisely determined, although it is plausible HSP90 impacts each of these activation steps (Murphy JM 2020).
