ENZYME entry: EC 3.1.3.86

Accepted Name
phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase
Alternative Name(s)
SHIP
Reaction catalysed
a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol-3,4,5-trisphosphate) + H2O = a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol-3,4-bisphosphate) + phosphate
Comment(s)
  • This enzyme hydrolyzes phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3) to produce PtdIns(3,4)P2, thereby negatively regulating the PI3K (phosphoinositide 3-kinase) pathways.
  • The enzyme also shows activity toward PtdIns(1,3,4,5)P4.
  • The enzyme is involved in several signal transduction pathways in the immune system leading to an adverse range of effects.
  • Formerly EC 3.1.3.n1.
