Function

Adapter required for innate immune defense against viruses (PubMed:24037184). 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 IFN-beta and RANTES (CCL5) (PubMed:24037184). Peroxisomal and mitochondrial MAVS act sequentially to create an antiviral cellular state (By similarity). 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 (By similarity). May activate the same pathways following detection of extracellular dsRNA by TLR3 (By similarity). May protect cells from apoptosis (By similarity). Involved in NLRP3 inflammasome activation by mediating NLRP3 recruitment to mitochondria (PubMed:23582325).

Activity summary

MAVS also known as mitochondrial antiviral-signaling protein is a critical adaptor protein involved in the innate immune response to viral infections. This protein with a molecular weight of approximately 56 kDa is expressed on the mitochondrial membrane. It plays a major role in antiviral defense by transmitting signals from cytosolic pattern recognition receptors like RIG-I-like receptors to initiate downstream immune responses. MAVS can also be referred to as IPS-1 VISA or CARDIF in scientific literature.

Biological function summary

The MAVS protein activates important signaling cascades to produce type I interferons and other cytokines which are essential in the antiviral response. MAVS forms a complex with other proteins on the mitochondrial membrane helping to coordinate a rapid immune reaction to viral pathogens. It acts by amplifying the signal from RIG-I and MDA5 facilitating their role in the recognition of viral RNA. By recruiting downstream signaling molecules MAVS enables the activation of transcription factors like IRF3 and NF-kB.

Pathways

MAVS plays a central role in the signaling pathways that regulate innate immunity including the RIG-I-like receptor signaling pathway and the NF-kB pathway. It interacts with various proteins such as TRIF and STING in the pathways to modulate immune responses. These pathways help trigger the production of antiviral substances and maintain homeostasis within the body's defense mechanisms. MAVS provides a platform for the assembly of signaling complexes which are necessary for the propagation and amplification of the immune response signal.

Associated diseases and disorders

MAVS is associated with conditions such as viral infections and autoimmune diseases. Dysregulation of MAVS activity has been linked to systemic lupus erythematosus where abnormal immune signaling may occur. MAVS also has connections with other proteins such as TRAF3 and TRAF6 which contribute to disease pathogenesis. Understanding the role of MAVS in these conditions may provide insights into therapeutic targets for improving disease outcomes.
