Predicted to enable several functions, including ATP binding activity; RNA binding activity; and RNA helicase activity. Acts upstream of or within positive regulation of mRNA splicing, via spliceosome and positive regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in submandibular gland primordium; testis; and vibrissa. Human ortholog(s) of this gene implicated in intellectual disability. Orthologous to human EIF4A3 (eukaryotic translation initiation factor 4A3). [provided by Alliance of Genome Resources, Apr 2022]
