Implicated in nucleolar organization, ribosome biogenesis, protein synthesis and cytoplasmic dsRNA sensing. Stimulates RNA polymerase I transcription of the 47S precursor rRNA. Associates with ribosomal DNA (rDNA) loci where it is involved in POLR1A recruitment. In the cytoplasm, promotes elongation-competent 80S ribosome assembly at the late stage of mRNA translation initiation. Senses cytosolic dsRNA mediating NLRP3 inflammasome formation in macrophages and type I interferon production in myeloid dendritic cells. Required for NLRP3 activation induced by viral dsRNA and bacterial RNA. In dendritic cells, required for induction of type I interferon production induced by cytoplasmic dsRNA via the activation of MAPK and NF-kappa-B signaling pathways. Source: Recombinant protein corresponding to aa1-450 from human Putative ATP-dependent RNA helicase DHX33, fused to 6X His-Tag at N-terminal, expressed in E.coli.
