Predicted to enable inositol pentakisphosphate 2-kinase activity and molecular adaptor activity. Predicted to be involved in inositol phosphate biosynthetic process; inositol phosphorylation; and positive regulation of transcription of nucleolar large rRNA by RNA polymerase I. Predicted to act upstream of or within phosphorylation. Predicted to be located in nucleolus. Predicted to be active in nucleus. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and sensory organ. Orthologous to human IPPK (inositol-pentakisphosphate 2-kinase). [provided by Alliance of Genome Resources, Apr 2022]
