CC -!- FUNCTION: Bifunctional inositol kinase that acts in concert with the
CC IP6K kinases to synthesize the diphosphate group-containing inositol
CC pyrophosphates diphosphoinositol pentakisphosphate, PP-InsP5, and bis-
CC diphosphoinositol tetrakisphosphate, (PP)2-InsP4. PP-InsP5 and (PP)2-
CC InsP4, also respectively called InsP7 and InsP8, may regulate a variety
CC of cellular processes, including apoptosis, vesicle trafficking,
CC cytoskeletal dynamics, and exocytosis. Phosphorylates inositol
CC hexakisphosphate (InsP6). {ECO:0000256|RuleBase:RU365032}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1D-myo-inositol hexakisphosphate + ATP = 1-diphospho-1D-myo-
CC inositol 2,3,4,5,6-pentakisphosphate + ADP; Xref=Rhea:RHEA:37459,
