At the plasma membrane, synaptojanin-1 aka Synaptic inositol-1,4,5-trisphosphate 5-phosphatase 1 (SYNJ1) (Guo et al. 1999), -2 (SYNJ2) and some myotubularins (MTMs) dephosphorylate phosphatidylinositol 3-phosphate (PI3P) to phosphatidylinositol (PI). The MTMs involved are: myotubularin (MTM1) (Cao et al. 2007, Tronchere et al. 2004, Schaletzky et al. 2003, Laporte et al. 2002, Kim et al. 2002) and myotubularin-related proteins 1 (MTMR1) (Kim et al. 2002, Tronchere et al. 2004), 3 (MTMR3) (Kim et al. 2002, Zhao et al. 2001, Walker et al. 2001, Lorenzo et al. 2005), 6 (MTMR6) (Schaletzky et al. 2003, Kim et al. 2002, Choudhury et al. 2006), and 14 (MTMR14) (Tosch et al. 2006).
