Results, PTPL1-FERM domain binds PtdIns(4,5)P2 in vitro,paragraph 1, lines 12-16 (p. 2524) currently read:

A very weak interaction with PtdIns(3,4,5)P3 was sometimes observed, whereas no interaction was detected with nonphosphorylated phosphatidylinositol and other control phospholipids (PA, PS, LPA, LPC, PE,PE, S1P).

Correct version: A very weak interaction with PtdIns(3)P was sometimes observed, whereas no interaction was detected with nonphosphorylated phosphatidylinositol and other control phospholipids (PA, PS, LPA, LPC, PE,PC, S1P).
