Functioni

Required for innate immune defense against viruses. Acts downstream of DDX58/RIG-I 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 IFN-beta and RANTES (CCL5). Peroxisomal and mitochondrial MAVS act sequentially to create an antiviral cellular state. 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. May activate the same pathways following detection of extracellular dsRNA by TLR3. May protect cells from apoptosis (By similarity).By similarity

Self-associates and polymerizes (via CARD domains) to form 400 nM long three-stranded helical filaments on mitochondria, filament nucleation requires interaction with DDX58/RIG-I whose CARD domains act as a template for filament assembly (By similarity). Interacts with DDX58/RIG-I, IFIH1/MDA5, TRAF2, TRAF6 and C1QBP. May interact with IRF3, FADD, RIPK1, IKBKE, CHUK and IKBKB. Interacts with NLRX1. Interaction with NLRX1 requires the CARD domain. Interacts with PSMA7. Interacts with TRAFD1. Interacts (via C-terminus) with PCBP2 in a complex containing MAVS/IPS1, PCBP2 and ITCH. Interacts with CYLD. Interacts with SRC. Interacts with DHX58/LGP2 and IKBKE. Interacts with TMEM173/MITA. Interacts with IFIT3 (via N-terminus). Interacts with TBK1 only in the presence of IFIT3. Interacts with MUL1.
