Predicted to enable protein kinase inhibitor activity. Predicted to be involved in maturation of LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be active in nucleolus. Is expressed in several structures, including anterior endoderm; anterior endoderm anlage; embryonic/larval midgut; embryonic/larval midgut primordium; and larval muscle cell. Orthologous to human PAK1IP1 (PAK1 interacting protein 1).
