a double strand RNA binding protein (dsRBP). Interacts with TRBP and Dicer to stimulate the cleavage of double-stranded or short hairpin RNA to siRNA. Appears to have a pro-apoptotic function that may be suppressed in the presence of growth factor. Activates the interferon-induced protein kinase PKR. Three alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
