Predicted to enable several functions, including ATP binding activity; RNA binding activity; and RNA helicase activity. Predicted to be involved in several processes, including mRNA metabolic process; negative regulation of selenocysteine insertion sequence binding activity; and regulation of translation. Predicted to be located in several cellular components, including dendrite; neuronal cell body; and nucleoplasm. Predicted to be part of U2-type catalytic step 1 spliceosome; catalytic step 2 spliceosome; and exon-exon junction complex. Predicted to be active in nucleolus. 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]
