PI-3 kinase signaling pathway is terminated by

PTEN phosphatase, which hydrolyzes the 3-phosphate

in PI 3-phosphates.

PTEN can remove phosphate groups attached to serine,

threonine, and tyrosine residues in proteins, its ability to

remove the 3-phosphate from PI(3,4,5)P3 is its major function in cells.
