PPIP5K2
Diphosphoinositol pentakisphosphate kinase 2 is a protein that in humans is encoded by the PPIP5K2 gene.
Function
Inositol phosphates and diphosphoinositol phosphates, also known as inositol pyrophosphates, act as cell signaling molecules.HISPPD1 has both IP6 kinase and PP-IP5 kinase activities that produce the high-energy pyrophosphates PP-IP5 and PP2-IP4, respectively.
