Reaction: PI(3,5)P2 is dephosphorylated to PI5P by MTMR9-bound MTMR6 or MTMR8 at the plasma membrane
- in pathway: Synthesis of PIPs at the plasma membrane
Formation of a complex with MTMR9 results in a 30-fold increase of phosphatidylinositol-(3,5)-bisphosphate 3-phosphatase catalytic activity of MTMR6 and a modest increase in the catalytic activity of MTMR8 (Zou et al. 2009, Zou et al. 2012).
