FunFam 5: phosphatidylinositol 3,4,5-trisphosphate 5-phospha...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase. [EC: 3.1.3.86]
1-phosphatidyl-1D-myo-inositol 3,4,5-triphosphate + H(2)O = 1-phosphatidyl-1D-myo-inositol 3,4-diphosphate + phosphate.
  • This enzyme hydrolyzes phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P(3)) to produce PtdIns(3,4)P(2), thereby negatively regulating the PI3K (phosphoinositide 3-kinase) pathways.
  • The enzyme also shows activity toward PtdIns(1,3,4,5)P(4).
  • 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.
