    Summary
    Predicted to enable RNA binding activity and RNA helicase activity. Involved in flight behavior; neuromuscular junction development; and ribonucleoprotein complex assembly. Located in Cajal body and cytoplasm. Part of SMN complex and cytoplasmic U snRNP body. Is expressed in eye disc; nurse cell; and oocyte. Orthologous to human DDX20 (DEAD-box helicase 20).
