Enables RNA binding activity; ribonucleoprotein complex binding activity; and translation regulator activity. Involved in several processes, including cellular response to brain-derived neurotrophic factor stimulus; cellular response to selenite ion; and regulation of translation. Located in several cellular components, including dendrite; neuronal cell body; and nucleus. Part of ribonucleoprotein complex. Is active in glutamatergic synapse and postsynaptic cytosol. 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]
