Mitochondrial antiviral signaling protein

VISA, IPS-1, MAVS, Cardif
This gene encodes an intermediary protein necessary in the virus-triggered beta interferon signaling pathways. It is required for activation of transcription factors which regulate expression of beta interferon and contributes to antiviral immunity. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011] (from NCBI)
Top mentioned proteins: RIG-I, ACID, Interferon Regulatory Factor-3, MDA5, CAN

Ritter et al., Braunschweig, Germany. In Proc Natl Acad Sci U S A, Feb 2016
The mitochondrial antiviral signaling protein (MAVS) is a central signal transduction hub in innate immunity that is activated by a receptor-induced conversion into helical superstructures (filaments) assembled from its globular caspase activation and recruitment domain.

Walkley et al., Australia. In Wiley Interdiscip Rev Rna, Jan 2016
Further analysis of this observation has lead to the conclusion that editing by ADAR1 is required to prevent activation of the cytosolic innate immune system, primarily focused on the dsRNA sensor MDA5 and leading to downstream signaling via MAVS.

These RNAs are detected via a mitochondrial antiviral signaling protein (MAVS)-dependent RNA sensing pathway or reverse-transcribed and detected via the cGAS-cGAMP-STING pathway, triggering a second, sustained wave of signaling that promotes specific immunoglobulin M production.
