CC -!- FUNCTION: Multifunctional ATP-dependent RNA helicase. The ATPase
CC activity can be stimulated by various ribo-and deoxynucleic acids
CC indicative for a relaxed substrate specificity. In vitro can unwind
CC partially double-stranded DNA with a preference for 5'-single-stranded
CC DNA overhangs. Involved in many cellular processes, which do not
CC necessarily require its ATPase/helicase catalytic activities. Involved
CC in the regulation of transcription and translation initiation. Involved
CC in innate immunity (By similarity). Involved in both stress and
CC inflammatory responses (By similarity). May negatively regulate
CC extrinsic apoptotic signaling pathway via death domain receptors. May
CC be involved in mitotic chromosome segregation (By similarity). Required
CC for canonical Wnt signaling involved in anteroposterior neural
CC patterning (PubMed:23413191). {ECO:0000250|UniProtKB:O00571,
CC ECO:0000250|UniProtKB:Q62167, ECO:0000269|PubMed:23413191}.

CC the cytosol. {ECO:0000250|UniProtKB:O00571}.
CC -!- DEVELOPMENTAL STAGE: Widely expressed throughout embryogenesis. At
CC gastrula stage (st. 10.5), equal expression in ventral and dorsal
CC marginal zones. At neurula stage (st. 18), highest expression levels in
CC ectodermal cells. {ECO:0000269|PubMed:23413191}.
CC -!- DISRUPTION PHENOTYPE: Morpholino knockdown of the protein causes
CC anteriorization of embryos, that exhibit enlarged heads and eyes,
CC shortened tails and defective melanocyte and eye pigmentation.
CC {ECO:0000269|PubMed:23413191}.
CC -!- SIMILARITY: Belongs to the DEAD box helicase family. DDX3/DED1
CC subfamily. {ECO:0000305}.
