Predicted to enable U3 snoRNA binding activity and rRNA binding activity. Predicted to be involved in maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be part of small-subunit processome. Predicted to be active in nucleolus. Is expressed in embryonic/larval hypodermal muscle cell. Orthologous to human UTP25 (UTP25 small subunit processome component).
