| Comment(s) |
|---|
- In humans, this enzyme, along with EC 2.7.1.127, EC 2.7.1.140 and
EC 2.7.1.158 is involved in the production of inositol
hexakisphosphate (InsP(6)).
- InsP(6) is involved in many cellular processes, including mRNA export
from the nucleus.
- Yeast do not have this enzyme, so produce InsP(6) from Ins(1,4,5)P(3)
by the actions of EC 2.7.1.151 and EC 2.7.1.158.
- The enzymes from animals and plants also have the activity of
EC 2.7.1.134.
