CC -!- FUNCTION: Bifunctional inositol kinase that acts in concert with the
CC IP6K kinases IP6K1, IP6K2 and IP6K3 to synthesize the diphosphate
CC group-containing inositol pyrophosphates diphosphoinositol
CC pentakisphosphate, PP-InsP5, and bis-diphosphoinositol
CC tetrakisphosphate, (PP)2-InsP4. PP-InsP5 and (PP)2-InsP4, also
CC respectively called InsP7 and InsP8, regulate a variety of cellular
CC processes, including apoptosis, vesicle trafficking, cytoskeletal
CC dynamics, exocytosis, insulin signaling and neutrophil activation.
CC Phosphorylates inositol hexakisphosphate (InsP6) at position 1 to
CC produce PP-InsP5 which is in turn phosphorylated by IP6Ks to produce
CC (PP)2-InsP4. Alternatively, phosphorylates PP-InsP5 at position 1,
CC produced by IP6Ks from InsP6, to produce (PP)2-InsP4. Activated when
CC cells are exposed to hyperosmotic stress.
CC {ECO:0000256|ARBA:ARBA00037056}.
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}.
