Rabbit Anti-Human MDA5 monoclonal antibody for FC, ICC, IHC-P, IF, WB. Melanoma differentiation associated gene 5, MDA5, is a pattern recognition receptor to transmit the signal.Once activated, both proteins signal through IPS-1 activating transcription factors NF- kappaB and IRF-3 and ultimately activating apoptosis, cytokine signaling, and inflammation. RIG-I is essential for signaling by influenza A, influenza B, human respiratory syncytial virus, paromyxoviruses, Japanese encephalitis virus. MDA5 is essential for signaling by picornavirus. Both RIG-I and MDA5 are responsible for signaling by West Nile virus.
