May be involved in transcription termination by RNA polymerase III. Binds RNA and DNA. Binds to precursors of RNA polymerase III transcripts. May play a specialized role during fly development. Expressed throughout embryonic, larval, pupal, and adult development. Expression throughout the embryo is followed by a restricted pattern of mesodermal expression that is later confined to the visceral mesoderm, gonads, gut, and salivary glands.
