DHX36 a multifunctional ATP-dependent helicase that unwinds G-quadruplex (G4) structures (helical structures containing guanine tetrads). Plays a role in deadenylation and degradation of mRNAs containing in their 3'-UTR consensus AU-rich elements (AREs). Plays a role in many biological processes such as genomic integrity, transcriptional regulation, and as a sensor to initiate antiviral responses. Plays a role in post-transcriptional regulation. For example, it unwinds a G4-RNA structure located in the 3'-UTR polyadenylation site of the pre-mRNA TP53 and stimulates TP53 pre-mRNA 3'-end processing in response to ultraviolet (UV)-induced DNA damage. Converts the G4-RNA structure present in telomerase RNA template component (TREC) into double-stranded RNA that acts as a template boundary ensuring accurate reverse transcription. Binds to the precursor-microRNA-134 (pre-miR-134) terminal loop and regulates its transport into the synapto-dendritic compartment, where it is involved in the pre-miR-134-dependent inhibition of target gene expression and the control of dendritic spine size. Plays a role in the regulation of cytoplasmic mRNA translation and mRNA stability. Component of a multi-helicase-TICAM1 complex that acts as a cytoplasmic sensor of viral double-stranded RNA (dsRNA) and plays a role in the activation of a cascade of antiviral responses including the induction of proinflammatory cytokines via the adapter molecule TICAM1. Required for early embryonic development and hematopoiesis. Involved in the regulation of cardioblast differentiation and proliferation during heart development. Involved in spermatogonia differentiation. May play a role in ossification. Belongs to the DEAD box helicase family. DEAH subfamily. Highly expressed in testis. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
