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 be located in nucleolus. Predicted to be active in nucleus. Orthologous to human IPPK (inositol-pentakisphosphate 2-kinase). [provided by Alliance of Genome Resources, Apr 2022]
