NLR family member X1 (NLRX1)

Participates in antiviral signaling. Acts as a negative regulator of MAVS-mediated antiviral responses, through the inhibition of this virus-induced RLH (RIG-like helicase)-MAVS interaction (PubMed:18200010).

Instead, promotes autophagy by interacting with TUFM and then recruiting the autophagy- related proteins ATG5 and ATG12 (PubMed:22749352). Regulates also MAVS-dependent NLRP3 inflammasome activation to attenuate apoptosis (PubMed:27393910).
