Activates1
Because the interaction of PI(4,5)P(2) with PTEN's N-terminal domain is diminished by this mutation, we hypothesize that the interaction of PTEN's N-terminal domain with the phosphatase domain is impacted by the H93R mutation, preventing PI(4,5)P(2) from inducing the conformational change that activates phosphatase activity. (nih.gov)
Inositol1
