Human MAVS Antibody

Mitochondrial antviral signaling protein (MAVS, also known as IPS-1, VISA, and CARDIF) is a ubiquitous, tail-anchored membrane protein inserted in the outer mitochondrial membrane (OMM), and is also found in the peroxisomal membrane and the mitochondrial associated membrane of the endoplasmic reticulum. Peroxisomal MAVS has been implicated in type II IFN-dependent antiviral response, while mitochondrial MAVS mediates longer lasting type I IFN dependent antiviral response. Mitochondrial reactive oxygen species (mROS) induce oligomerization of MAVS in the outer membrane plane of mitochondria to induce innate immunity to viral infection. MAVS undergoes RIG-I-like receptors (RLR)-induced formation of higher order structures ranging from dimers to prion-like aggregates that lead to the recruitment and activation of signaling proteins culminating in the activation of the transcription factors IRF-3 and NF-kappa B and transcription of IFNs
