Predicted to enable flavonoid binding activity and inositol hexakisphosphate 5-kinase activity. Predicted to be involved in several processes, including cellular response to flavonoid; organophosphate biosynthetic process; and phosphate ion transport. Predicted to act upstream of or within lipid metabolic process and phosphorylation. Located in nucleus. Is expressed in several structures, including alimentary system; heart; nervous system; respiratory system; and sensory organ. Orthologous to human IP6K2 (inositol hexakisphosphate kinase 2).
