Comments

Comment Type Description
Catalytic Activity ATP + 1D-myo-inositol 1-diphosphate 2,3,4,5,6- pentakisphosphate = ADP + 1D-myo-inositol 1,5-bis(diphosphate) 2,3,4,6-tetrakisphosphate.
Catalytic Activity ATP + 1D-myo-inositol hexakisphosphate = ADP + 1D-myo-inositol 5-diphosphate 1,2,3,4,6-pentakisphosphate.
Function Converts inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). Converts 1,3,4,5,6-pentakisphosphate (InsP5) to PP-InsP4 (By similarity)
Similarity Belongs to the inositol phosphokinase (IPK) family
Subcellular Location Cytoplasm . Nucleus .
