Regulator of G-protein signaling 19 (RGS19) and its partner Gα-inhibiting activity polypeptide 3 (GNAI3) are required for zVAD-induced autophagy and cell death in L929 cells.

ABSTRACT: Autophagy has diverse biological functions and is involved in many biological processes. The L929 cell death induced by the pan-caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp-(OMe)-fluoromethyl ketone (zVAD) was shown to be an autophagy-mediated death for which RIP1 and RIP3 were both required. It was also reported that zVAD can induce a small amount of TNF production, which was shown to be required for zVAD-induced L929 cell death, arguing for the contribution of autophagy in the zVAD-induced L929 cell death. In an effort to study RIP3 mediated cell death, we identified regulator of G-protein signaling 19 (RGS19) as a RIP3 interacting protein. We showed that RGS19 and its partner Gα-inhibiting activity polypeptide 3 (GNAI3) are involved in zVAD-, but not TNF-, induced cell death. The rol
