Predicted to enable DNA binding activity and double-stranded RNA binding activity. Predicted to be involved in positive regulation of DNA-templated transcription. Part of catalytic step 2 spliceosome and precatalytic spliceosome. Is expressed in several structures, including anterior endoderm; embryonic/larval midgut primordium; ganglia; larval muscle cell; and sensory nervous system primordium. Orthologous to human ILF2 (interleukin enhancer binding factor 2).
