inositol-1,3,4-trisphosphate 5/6-kinase;
Ins(1,3,4)P3 5/6-kinase;
inositol trisphosphate 5/6-kinase

ATP:1D-myo-inositol 1,3,4-trisphosphate 5-phosphotransferase
(1) ATP + 1D-myo-inositol 1,3,4-trisphosphate = ADP + 1D-myo-inositol 1,3,4,5-tetrakisphosphate [RN:R03428];
(2) ATP + 1D-myo-inositol 1,3,4-trisphosphate = ADP + 1D-myo-inositol 1,3,4,6-tetrakisphosphate [RN:R03429]

1D-myo-inositol 1,3,4,5-tetrakisphosphate [CPD:C01272];
1D-myo-inositol 1,3,4,6-tetrakisphosphate [CPD:C04477]
In humans, this enzyme, along with EC (inositol-trisphosphate 3-kinase), EC (inositol-tetrakisphosphate 5-kinase) and EC (inositol pentakisphosphate 2-kinase) is involved in the production of inositol hexakisphosphate (InsP6). InsP6 is involved in many cellular processes, including mRNA export from the nucleus [2]. Yeasts do not have this enzyme, so produce InsP6 from Ins(1,4,5)P3 by the actions of EC (inositol-polyphosphate multikinase) and EC (inositol-pentakisphosphate 2-kinase) [2]. The enzymes from animals and plants also have the activity of EC, inositol-tetrakisphosphate 1-kinase.
