Product Description

This intracellular Detection Set is for measuring protein levels in cell lysates.  It allows to quantitatively determine:
a. Levels of MDA5
b. Interferon response since MDA5 is an interferon inducible gene
b. Virus infection response
General Information
The innate immune response to viruses is initiated upon detection of viral RNA generated during the life cycle of most viruses [1]. Recognition of the viral RNA is mediated by either the two cytoplasmic RNA helicases Retinoic acid Inducible Gene-1 (RIG-I ; Ddx58) and Melanoma Differentiation Associated gene 5 (MDA5 / Helicard; Ifih1) [2] or by Toll-like Receptor 3 (TLR3) located to an endosomal-like compartment [3]. RIG-I and MDA5 belongs to the family of RIG-I like receptor (RLR) together with the protein LGP2 whose function is still elusive [4, 5]. Upon binding to RNA, RIG-I or MDA5 binds a new mediator named Cardif, MAVS (mitochondrial antiviral signalling), IPS-1 (interferon-β promoter stimulator 1) or VISA (virus-induced signalling adapter) [6, 7]. Cardif/ MAVS/ IPS-1/ VISA then interacts with several TRAFs molecules, leading to the activation of regulatory kinases, such as TBK1, IKKε , and the IKKα/β/γ complex. These kinases activate respective transcription factors, IRF-3, IRF-7, and NF-κB that participate in the activation of IFN and other inflammatory cytokine genes. RIG-I is activated by dsRNA and 5′-ppp RNA while only poly I: C acts as a chemical agonist for MDA5. The physiological agonist of MDA5 has still to be discovered. Mda-5 is an early response gene inducible by IFN and tumor necrosis factor-α, responding predominantly to IFN-β [8].

General Information
MDA5 is a highly conserved helicase whose ATPase activity can be stimulated by RNA and less potently by DNA. It contains two N-terminal CARD domains and a C-terminal helicase domain. The helicase domain, once freed from the CARD domains, then translocates from the cytoplasm to the nucleus where it acts on chromatin architecture. This could allow a more easy access of CAD, thereby accelerating the degradation of genomic DNA.

General Information
RIG-I (retinoic acid-inducible gene I; Ddx58), a member of the DEAD-box RNA helicases, is activated by cytoplasmic dsRNA produced during the viral replication. The protein is characterized by a N-terminal region with two caspase recruitment domains (CARD) and a C-terminal region harboring potential ATP-dependent RNA helicase activity. RIG-1 recruits the CARD adaptor inducing IFN-β (Cardif) in a CARD-CARD-dependent manner resulting in NF-κB and IRF3 activation.

General Information
The innate immune response to viruses is initiated upon detection of viral RNA generated during the life cycle of most viruses [1]. Recognition of the viral RNA is mediated by either the two cytoplasmic RNA helicases Retinoic acid Inducible Gene-1 (RIG-I ; Ddx58) and Melanoma Differentiation Associated gene 5 (MDA5 / Helicard) [2] or by Toll-like Receptor 3 (TLR3) located to an endosomal-like compartment [3]. RIG-I and MDA5 belong to the family of RIG-I like receptor (RLR) together with the protein LGP2 whose function is still elusive [4, 5]. Upon binding to RNA, RIG-I or MDA5 binds a new mediator named Cardif, MAVS, IPS-1 or VISA [6, 7] that signals through transcription factors, such as IRF-3, IRF-7, and NF-κB leading to the activation of interferons (IFNs) and other inflammatory cytokine genes. RIG-I is activated by dsRNA and 5′-ppp RNA. RIG-I has been shown to trigger innate immune signaling pathways during infection by orthomyxoviruses, rhabdovirus, vesicular stomatitis virus, and paramyxoviruses; and possibly by the filovirus Ebola virus and by the Epstein-Barr virus [8]. Virus infection induces a rapid production of IFN-α/β that leads to expression of hundreds of interferon-stimulated genes (ISGs) whose products direct antiviral actions. RIG-I belongs to the ISG gene family and monitoring its levels using the RIG-I (human) Detection Set (IC) can be used as indicator of IFN production and virus infection.
