Summary: Enables RNA binding activity; RNA helicase activity; and eukaryotic initiation factor 4G binding activity. Involved in positive regulation of formation of translation preinitiation complex; spliceosomal complex disassembly; and translational initiation. Located in cytoplasmic stress granule and nucleus. Used to study childhood medulloblastoma. Human ortholog(s) of this gene implicated in colorectal cancer and syndromic X-linked intellectual disability. Orthologous to human DDX3X (DEAD-box helicase 3 X-linked) and DDX3Y (DEAD-box helicase 3 Y-linked). [provided by Alliance of Genome Resources, Nov 2024]
