Western blot analysis of extracts from THP-1(lane 2(20ug) ,Jurkat(lane 3(20ug) and HEK293(lane 4(20ug) using MDA5 Antibody (HY-P82654) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
Immunocytochemistry analysis of HepG2 cells labeling MDA5 with MDA5 Antibody (HY-P82654) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with MDA5 Antibody (HY-P82654) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L（HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background

Function：Innate immune receptor which acts as a cytoplasmic sensor of viral nucleic acids and plays a major role in sensing viral infection and in the activation of a cascade of antiviral responses including the induction of type I interferons and pro-inflammatory cytokines (PubMed:28594402, PubMed:32169843, PubMed:33727702). Its ligands include mRNA lacking 2'-O-methylation at their 5' cap and long-dsRNA (>1 kb in length) (PubMed:22160685). Upon ligand binding it associates with mitochondria antiviral signaling protein (MAVS/IPS1) which activates the IKK-related kinases: TBK1 and IKBKE which phosphorylate interferon regulatory factors: IRF3 and IRF7 which in turn activate transcription of antiviral immunological genes, including interferons (IFNs); IFN-alpha and IFN-beta. Responsible for detecting the Picornaviridae family members such as encephalomyocarditis virus (EMCV), mengo encephalomyocarditis virus (ENMG), and rhinovirus (PubMed:28606988). Detects coronavirus SARS-CoV-2 (PubMed:33440148, PubMed:33514628). Can also detect other viruses such as dengue virus (DENV), west Nile virus (WNV), and reovirus. Also involved in antiviral signaling in response to viruses containing a dsDNA genome, such as vaccinia virus. Plays an important role in amplifying innate immune signaling through recognition of RNA metabolites that are produced during virus infection by ribonuclease L (RNase L). May play an important role in enhancing natural killer cell function and may be involved in growth inhibition and apoptosis in several tumor cell lines

Subcellular Localization：Cytoplasm; Nucleus; Mitochondrion

Expression：
Tissue_specificity:Widely expressed, at a low level. Expression is detected at slightly highest levels in placenta, pancreas and spleen and at barely levels in detectable brain, testis and lung

Induction:By interferon (IFN) and TNF

Isoforms & Post-Translational Modification：Q9BYX4 has 2 isomers: Q9BYX4-1: 116689 Da (predicted); Q9BYX4-2: 25129 Da (predicted).
Sumoylated. Sumoylation positively regulates its role in type I interferon induction and is enhanced by PIAS2-beta;Ubiquitinated by RNF125, leading to its degradation by the proteasome (PubMed:17460044). USP17/UPS17L2-dependent deubiquitination positively regulates the receptor (PubMed:20368735). Ubiquitinated by TRIM25 via 'Lys-63'-linked ubiquitination, promoting activation of IFIH1/MDA5 (PubMed:30193849). Ubiquitinated by TRIM40 via 'Lys-48'-linked ubiquitination; leading to proteasomal degradation (PubMed:29117565). Ubiquitinated by TRIM65 via 'Lys-63'-linked ubiquitination, promoting activation of IFIH1/MDA5 (PubMed:28594402);ISGylated by ISG15. ISGylation increases upon infection with dengue (DENV) or Zika (ZIKV) viruses. ISGylation at Lys-23 and Lys-43 is dependent of dephosphorylation at Ser-88, regulates mitochondrial translocation and oligomerization. Essential for IFIH1/MDA5-mediated cytokine responses and restriction of virus replication;Phosphorylated at Ser-88 (PubMed:23499489, PubMed:33727702). Dephosphorylated by phosphatases PPP11CA/PPP11CC; dephosphorylation precedes and is required for ISGylation (PubMed:23499489, PubMed:33727702);During apoptosis, processed into 3 cleavage products. The helicase-containing fragment, once liberated from the CARD domains, translocate from the cytoplasm to the nucleus. The processed protein significantly sensitizes cells to DNA degradation;(Microbial infection) Cleaved and inactivated by the protease 2A of coxsackievirus B3, poliovirus and enterovirus 71 allowing the virus to disrupt the host type I interferon production

Subunit：Monomer in the absence of ligands and homodimerizes in the presence of dsRNA ligands. Can assemble into helical or linear polymeric filaments on long dsRNA (PubMed:33727702). Interacts with MAVS/IPS1. Interacts (via the CARD domains) with TKFC, the interaction is inhibited by viral infection (PubMed:17600090). Interacts with PCBP2. Interacts with NLRC5. Interacts with PIAS2-beta. Interacts with DDX60. Interacts with ANKRD17. Interacts with IKBKE (PubMed:17600090). Interacts with ATG5 and ATG12, either as ATG5 and ATG12 monomers or as ATG12-ATG5 conjugates (PubMed:17709747). Interacts with ZCCHC3; leading to activate IFIH1/MDA5 (PubMed:30193849). Interacts with RNF123 (PubMed:27312109). Interacts with DDX3X (PubMed:20127681). Interacts with NOD1; this interaction promotes transcription of antiviral genes and inhibition of viral replication (PubMed:32169843). Interacts with ECSIT; this interaction bridges IFIH1 to the MAVS complex at the mitochondrion (PubMed:25228397)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
