    Summary
    Enables poly(U) RNA binding activity. Involved in central nervous system development and negative regulation of mRNA 3'-end processing. Located in Cajal body. Is expressed in several structures, including ganglia; neuroblasts; neurons; sclerite; and sense organ. Orthologous to human ELAVL3 (ELAV like RNA binding protein 3).
