Figure 2. Post-translational regulation of RIP1-RIP3-MLKL-axis and its effect on cell survival and death pathways.

Figure 2

Multiple sites on RIP1 (A), RIP3 (B), and MLKL (C) protein have been revealed in the regulation of the balance between cell survival and death signaling by either phosphorylation or ubiquitylation. In addition, human RIP3 is O-GlcNAcylated at T467. P phosphorylation; Ub ubiquitylation. O O-GlcNAcylation. Yellow color of activated site indicates autophosphorylation for activation; Green color indicates inhibition; Red color indicates activation. Upstream molecules for specific sites in circle are also included (Green circle indicates inhibition; red circle indicates activation). Subsequent cellular responses/events are marked in squares.
