Function | Adapter required for innate immune defense against viruses (PubMed:16125763, PubMed:16127453, PubMed:16153868, PubMed:16177806, PubMed:19631370, PubMed:20451243, PubMed:23087404, PubMed:20127681, PubMed:21170385, PubMed:27992402, PubMed:37582970). Acts downstream of DHX33, RIGI and IFIH1/MDA5, which detect intracellular dsRNA produced during viral replication, to coordinate pathways leading to the activation of NF-kappa-B, IRF3 and IRF7, and to the subsequent induction of antiviral cytokines such as IFNB and RANTES (CCL5) (PubMed:16125763, PubMed:16127453, PubMed:16153868, PubMed:16177806, PubMed:19631370, PubMed:20451243, PubMed:23087404, PubMed:25636800, PubMed:20127681, PubMed:21170385, PubMed:20628368, PubMed:33110251, PubMed:27736772). Peroxisomal and mitochondrial MAVS act sequentially to create an antiviral cellular state (PubMed:20451243). Upon viral infection, peroxisomal MAVS induces the rapid interferon-independent expression of defense factors that provide short-term protection, whereas mitochondrial MAVS activates an interferon-dependent signaling pathway with delayed kinetics, which amplifies and stabilizes the antiviral response (PubMed:20451243). May activate the same pathways following detection of extracellular dsRNA by TLR3 (PubMed:16153868). May protect cells from apoptosis (PubMed:16125763). Involved in NLRP3 inflammasome activation by mediating NLRP3 recruitment to mitochondria (PubMed:23582325). |
Cellular Location | Mitochondrion outer membrane; Single-pass membrane protein. Mitochondrion. Peroxisome |
Tissue Location | Present in T-cells, monocytes, epithelial cells and hepatocytes (at protein level). Ubiquitously expressed, with highest levels in heart, skeletal muscle, liver, placenta and peripheral blood leukocytes. |

Background
Double-stranded RNA viruses are recognized in a celltype-dependent manner by the transmembrane receptor TLR3 (MIM603029) or by the cytoplasmic RNA helicases MDA5 (MIM 606951) andRIGI (ROBO3; MIM 608630). These interactions initiate signalingpathways that differ in their initial steps but converge in theactivation of the protein kinases IKKA (CHUK; MIM 600664) and IKKB(IKBKB; MIM 603258), which activate NFKB (see MIM 164011), or TBK1(MIM 604834) and IKKE (IKBKE; MIM 605048), which activate IRF3 (MIM603734). Activated IRF3 and NFKB induce transcription of IFNB(IFNB1; MIM 147640). For the TLR3 pathway, the intermediarymolecule before the pathways converge is the cytoplasmic proteinTRIF (TICAM1; MIM 607601). For RIGI, the intermediary protein ismitochondria-bound IPS1 (Sen and Sarkar, 2005 [PubMed16239922]).
