Myotubularin-related protein 14 (MTMR14, also known as Jumpy) belongs to the myotubularin family, whose members are dual-specificity phosphatases that act primarily to dephosphorylate phosphoinositides (PIs). They act specifically on PI3P and PI3,5P2, dephosphorylating them to form PIP and PI5P, respectively []. MTMR14 interacts with early autophagosomes and negatively regulates progression through the steps of autophagy []. It has been linked to the a congenital muscle disorder known as myopathy, centronuclear, 1 (CNM1) [].

This entry represents the PH-GRAM domain that binds to phosphoinositide lipid [].
