NLRX1 or NLR family member X1, short for nucleotide-binding oligomerization domain, leucine rich repeat containing X1, is an intracellular protein that plays a role in the immune system. It is also known as NOD-like receptor X1, NLR family, X1, NOD5, NOD9, and CLR11.3, and is a member of the NOD-like receptor family of pattern recognition receptors. NLRX1 was proposed to affect innate immunity to viruses by interfering with the mitochondrial antiviral signaling protein (MAVS)/retinoic-acid-inducible gene I (RIG-I) mitochondrial antiviral pathway.,[2] although this was recently questioned.[3][4]

NLRX1 has a unique protein structure composed of 3 protein domains: an N-terminal effector domain containing a mitochondrion localization signal; a central NACHT domain; a C-terminal leucine-rich repeat (LRR) domain.[5]

In humans, the NLRX1 protein is encoded by the NLRX1 gene.[6][7]
