GeneCards Summary for DHX58 Gene
DHX58 (DEXH (Asp-Glu-X-His) Box Polypeptide 58) is a Protein Coding gene. Among its related pathways are RIG-I/MDA5 mediated induction of IFN-alpha/beta pathways and RIG-I/MDA5 mediated induction of IFN-alpha/beta pathways. GO annotations related to this gene include helicase activity and single-stranded RNA binding. An important paralog of this gene is DDX58.
UniProtKB/Swiss-Prot for DHX58 Gene
Acts as a regulator of DDX58/RIG-I and IFIH1/MDA5 mediated antiviral signaling. Cannot initiate antiviral signaling as it lacks the CARD domain required for activating MAVS/IPS1-dependent signaling events. Can have both negative and positive regulatory functions related to DDX58/RIG-I and IFIH1/MDA5 signaling and this role in regulating signaling may be complex and could probably depend on characteristics of the infecting virus or target cells, or both. Its inhibitory action on DDX58/RIG-I signaling may involve the following mechanisms: competition with DDX58/RIG-I for binding to the viral RNA, binding to DDX58/RIG-I and inhibiting its dimerization and interaction with MAVS/IPS1, competing with IKBKE in its binding to MAVS/IPS1 thereby inhibiting activation of interferon regulatory factor 3 (IRF3). Its positive regulatory role may involve unwinding or stripping nucleoproteins of viral RNA thereby facilitating their recognition by DDX58/RIG-I and IFIH1/MDA5. Involved in the innate immune response to various RNA viruses and some DNA viruses such as poxviruses, and also to the bacterial pathogen Listeria monocytogenes. Can bind both ssRNA and dsRNA, with a higher affinity for dsRNA. Shows a preference to 5-triphosphorylated RNA, although it can recognize RNA lacking a 5-triphosphate.
