Reaction: PI3P is dephosphorylated to PI by MTM1:MTMR12

- in pathway: Synthesis of PIPs at the early endosome membrane
Binding of MTMR12 to MTM1 enhances phosphatidylinositol-3-phosphatase activity of MTM1 at cytosolic vesicular structures, presumably early or late endosomes (Caldwell et al. 1991, Nandurkar et al. 2003, Gupta et al. 2013).
Reaction - small molecule participants:
Pi [cytosol]
PI [early endosome membrane]
H2O [cytosol]
