Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.

PF00271Helicase conserved C-terminal domain (Helicase_C)Helicase conserved C-terminal domainThe Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.Domain

The RD domain binds viral RNA, activating the RIG-I ATPase by RNA-dependant dimerisation. The structure of RD contains a zinc-binding domain and is thought to confer ligand specificity [1].

RIG-I is a key cytosolic pattern-recognition receptors of the vertebrate innate immune system that form the first line of defense against RNA viral infection. RNA binding to RIG-I is mediated both by the C-terminal domain and by the helicase domain. The C-terminal domain specifically binds the 5'triphosphate end with a 10-fold higher affinity compared to 5'OH-dsRNA [1].
