NCBI and Uniprot Product Information
NCBI Description
Double-stranded RNA viruses are recognized in a cell type-dependent manner by the transmembrane receptor TLR3 (MIM 603029) or by the cytoplasmic RNA helicases MDA5 (MIM 606951) and RIGI (ROBO3; MIM 608630). These interactions initiate signaling pathways that differ in their initial steps but converge in the activation 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 (MIM 603734). Activated IRF3 and NFKB induce transcription of IFNB (IFNB1; MIM 147640). For the TLR3 pathway, the intermediary molecule before the pathways converge is the cytoplasmic protein TRIF (TICAM1; MIM 607601). For RIGI, the intermediary protein is mitochondria-bound IPS1 (Sen and Sarkar, 2005 [PubMed 16239922]).[supplied by OMIM]
Uniprot Description
MAVS: 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). May activate the same pathways following detection of extracellular dsRNA by TLR3. May protect cells from apoptosis. Interacts with DDX58/RIG-I, IFIH1/MDA5, TRAF2 and TRAF6. May interact with IRF3, FADD, RIPK1, CHUK and IKBKB. Does not interact with TBK1. Interacts with and is cleaved by HCV and hepatitis GB virus B NS3/4A proteases. Interacts with and is cleaved by HHAV protein 3ABC. 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. Present in T-cells, monocytes, epithelial cells and hepatocytes. Ubiquitously expressed, with highest levels in heart, skeletal muscle, liver, placenta and peripheral blood leukocytes. 3 isoforms of the human protein are produced by alternative splicing.
