Function
RNA helicase that, through its ATP-dependent unwinding of RNA, may function to promote message degradation by specific RNases. Seems to have growth suppressive properties. Involved in innate immune defense against viruses. Upon interaction with intracellular dsRNA produced during viral replication, triggers a transduction cascade involving MAVS/IPS1, which results in the activation of NF-kappa-B, IRF3 and IRF7 and the induction of the expression of antiviral cytokines such as IFN-beta and RANTES (CCL5). ATPase activity is specifically induced by dsRNA (By similarity). Essential for the production of interferons in response to picornaviruses.
Specificity
Natural and recombinant Mouse Interferon-induced helicase C domain-containing protein 1
Subcellular Location
Cytoplasm Nucleus May be found in the nucleus, during apoptosis.
Interacts with MAVS. Interacts with V protein of Sendai virus. Binding to paramyxoviruses V proteins prevents IFN-beta induction, and the further establishment of an antiviral state (By similarity). Interacts with PCBP2 (By similarity). Interacts with NLRC5.
