Mechanism of human PTEN localization revealed by heterologous expression in Dictyostelium

Phosphatase and tensin homolog (PTEN) is one of the most frequently mutated tumor suppressor genes in cancers. PTEN has a central role in phosphatidylinositol (3,4,5)-trisphosphate (PIP3) signaling and converts PIP3 to phosphatidylinositol (4,5)-bisphosphate at the plasma membrane. Despite its importance, the mechanism that mediates membrane localization of PTEN is poorly understood. Here, we generated a library that contains green fluorescent...
