Predicted to enable RNA strand annealing activity; RNA strand-exchange activity; and ribosomal small subunit binding activity. Predicted to be involved in eukaryotic translation initiation factor 4F complex assembly and formation of translation preinitiation complex. Located in dendrite and neuronal cell body. Is active in postsynapse. Orthologous to human EIF4B (eukaryotic translation initiation factor 4B). [provided by Alliance of Genome Resources, Apr 2022]
