General annotation (Comments)

Function

Acts as a phosphoinositide 5- and phosphoinositide 6-phosphatase and regulates cellular levels of inositol pentakisphosphate (InsP5) and inositol hexakisphosphate (InsP6) By similarity. May play a role in bone development (endochondral ossification).

Catalytic activity

Myo-inositol hexakisphosphate + H2O = myo-inositol pentakisphosphate (mixed isomers) + phosphate. Ref.1

Subcellular location

Endoplasmic reticulum lumen. Ref.2

Tissue specificity

Widely expressed with highest levels in kidney and liver. Expressed in chondrocytes with an elevated expression in hypertrophic chondrocytes. Ref.1 Ref.3

biophysicochemical properties

Kinetic parameters:

KM=6.9 µM for Ins(1,3,4,5)P4

Vmax=302 pmol/min/µg enzyme
