High-dose carteolol induced necroptotic protein expression in HCECs. (A) Western immunoblot images of RIPK1, RIPK3, MLKL and pMLKL proteins in 0.5–2% carteolol-treated HCECs. (B) The protein expression of RIPK1, RIPK3, MLKL and pMLKL were upregulated (P < 0.01), and the relative amount of each protein was expressed as a percentage (mean ± SD) of protein band density as compared that of β-actin at the same time-point (n = 3), while Nec-1 management manifested a significant inhibitory effect on the increased production of these proteins (P < 0.05 at the protein expression of RIPK3 with 2% cartelol-treated group, P < 0.01 at the other group). *P < 0.05, and **P < 0.01 vs control. (C) The activation of caspase-2 was measured by ELISA using monoclonal antibodies targeted against their active forms (P < 0.01). The 490 nm absorbance of each group was expressed as mean ± SD (n = 3). **P < 0.01 versus the blank control. (D) The caspase-8 was measured by ELISA using monoclonal antibodies targeted against their active forms (P < 0.05 at the caspase-8 activation with 2% cartelol-treated 2 h group, P < 0.01 at the other group). The 490 nm absorbance of each group was expressed as mean ± SD (n = 3). *P < 0.05, and **P < 0.01 versus the blank control.

Biological function summary
The MLKL protein acts as an executioner of cell death by forming a complex that disrupts the plasma membrane integrity. This process is downstream of receptor-interacting serine/threonine-protein kinase 3 (RIPK3) which phosphorylates MLKL to form the active necrosome complex. Active MLKL oligomerizes and migrates towards the inner leaflet of the plasma membrane binding to phosphatidylinositol phosphates which assists in pore formation and cellular rupture. The ability to measure MLKL activity levels such as via MLKL ELISA kits is important for understanding necrotic processes in detailed studies.
Pathways
MLKL is integrally involved in the necroptotic pathway alongside RIPK1 and RIPK3 which are key initiators of necroptosis. Phosphorylated MLKL acts downstream of RIPK3 resulting in cell death without caspase activation distinguishing necroptosis from apoptosis. MLKL and RIPK3 are tightly linked within this pathway with MLKL phosphorylation serving as a vital event for the execution phase. The necroptosis pathway is part of larger networks including inflammatory response pathways highlighting the importance of MLKL's role beyond sheer cell death.
