PHLPPL (PH domain leucine-rich repeat-containing protein phosphatase-like) is responsible for the dephosphorylation and subsequent inactivation of Akt. Akt is a signaling protein critical to the balance of cell survival and apoptosis. Dephosphorylation of Akt by PHLPPL has been demonstrated to trigger apoptosis and suppress tumor cell growth. PHLPPL is also known as PHLPPL2 and functions similarly to its relative, PHLPP1. Recent studies show that PHLPPL and PHLPP selectively terminate Akt-signaling by targeting specific Akt isoforms.
