At the late endosome membrane, myotubularin (MTM1), myotubularin-related protein 2 (MTMR2), myotubularin-related protein 4 (MTMR4), and myotubularin-related protein 7 (MTMR7) dephosphorylate phosphatidylinositol 3-phosphate (PI3P) to phosphatidylinositol (PI).

The following lists the above proteins with their corresponding literature references: MTM1 (Cao et al. 2007, Cao et al. 2008, Tsujita et al. 2004, Tronchere et al. 2004, Kim et al. 2002); MTMR2 (Cao et al. 2008, Kim et al. 2002); MTMR4 (Lorenzo et al. 2006); and MTMR7 (Mochizuki & Majerus 2003, Lorenzo et al. 2006).
