Predicted to enable RNA helicase activity and mRNA binding activity. Involved in several processes, including P-body assembly; determination of adult lifespan; and negative regulation of translation. Located in P granule; P-body; and cytoplasmic stress granule. Part of messenger ribonucleoprotein complex. Is expressed in several structures, including Z2; Z3; germ line; gonad; and neurons. Orthologous to human DDX6 (DEAD-box helicase 6). [provided by Alliance of Genome Resources, Apr 2022]
