Enables RNA stem-loop binding activity; ribonucleoprotein complex binding activity; and selenocysteine insertion sequence binding 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 dendrite and neuronal cell body. Part of ribonucleoprotein complex. Is active in glutamatergic synapse. Human ortholog(s) of this gene implicated in intellectual disability. Orthologous to human EIF4A3 (eukaryotic translation initiation factor 4A3); PARTICIPATES IN spliceosome pathway; mRNA decay pathway; RNA transport pathway; INTERACTS WITH 2,4-dibromophenyl 2,4,5-tribromophenyl ether; 4,4'-sulfonyldiphenol; 6-propyl-2-thiouracil.
