Involved in apoptosis. May have a role in rRNA processing and mRNA splicing. Associates with pre-rRNA precursors. ATP + H2O = ADP + H(+) + phosphate Interacts with AGO1 and AGO2. Interacts with GABARAP. Interacts with NOL8; the interaction is RNA-dependent. Localizes in the nucleolar-organizing region during ribosome biogenesis. Expressed in skin, lung and breast. Also expressed in the brain. Belongs to the DEAD box helicase family. DDX47/RRP3 subfamily. Truncated N-terminus.
