This is the N-terminal domain found in the Inositol hexakisphosphate and diphosphoinositol-pentakisphosphate kinase 2 (PPIP5K2), EC:2.7.4.24. Structure analysis of human PPIP5K2 indicate that this region forms alpha-beta-alpha domain [1].PPIP5K2 is one of the mammalian PPIP5K isoforms responsible for synthesis of diphosphoinositol polyphosphates (inositol pyrophosphates; PP-InsPs), regulatory molecules that function at the interface of cell signaling and organismic homeostasis [3].
