ATP-dependent RNA helicase DHX33 (DHX33)

Stimulates RNA polymerase I transcription of the 47S precursor rRNA. Associates with ribosomal DNA (rDNA) loci where it is involved in POLR1A recruiting (PubMed:21930779).

In the cytoplasm, promotes elongation-competent 80S ribosome assembly in the late phase of mRNA translation initiation (PubMed:26100019). Senses cytosolic dsRNA mediating NLRP3 inflammasome formation in macrophages and type I interferon production in myeloid dendritic cells (PubMed:23871209).
