Abstract

The PTEN tumor suppressor exerts phosphatase activity on PI(3,4,5)P3 in the plasma membrane and was recently reported to dimerize in cell models. Here we show that PTEN forms homodimers in vitro and determine a structural model of the complex from SAXS and Rosetta docking studies. PTEN's C-terminal tail is disordered on the monomer but presumable well-folded on the dimer, shedding new light on its regulatory role.
