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].

TRADD Protein Is an Essential Component of the RIG-like Helicase Antiviral Pathway: M.C. Michallet, et al.; Immunity 28, 651 (2008) Abstract
General Information
RIG-I (retinoic acid-inducible gene I; Ddx58) and MDA5 (melanoma differentiation-associated gene 5, also known as Ifih1 or Helicard) are proteins that sense viral replication intermediates, such as double-stranded RNA and triggers the host antiviral programs. These molecules signal the downstream activation of NF-κB and IFN regulatory factor (IRF) -3, which coordinately regulate the expression of type-I interferons.
Cardif (also called VISA/IPS-1/MAVS) is a new CARD (caspase activation and recruitment domain)-containing adaptor protein that interacts with the CARD domain of RIG-I and MDA5, leading to the activation of NF-κB and IRF3. Cardif is located to the mitochondrial outer membrane. Removal of the mitochondrial-targeting domain of cardif abolishes its ability to induce IFNs. Cardif is cleaved and inactivated by NS3-4A, a serine protease from hepatitis C virus known to block interferon-β production.

Characterization of three novel monoclonal antibodies against hepatitis C virus core protein: D. Moradpour, et al.; J. Med. Virol. 48, 234 (1996) Abstract
General Information
Hepatitis C virus (HCV) is the primary cause of non-A, non-B hepatitis and results in most HCV-infected people developing chronic infections, liver cirrhosis and hepatocellular carcinoma. The 21kDa core protein of HCV is well conserved among different HCV genotypes and may suppress hepatitis B virus replication in a phosphorylation dependent manner.
BACKGROUND/TECHNICAL INFORMATION Immunocytochemical staining of HCV core protein in transfected chimp hepatocytes yields a staining pattern consistent with cytoplasmic and vesicular staining.

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.
