Myotubularin-related protein 1 (MTMR1) is a member of the myotubularin family of dual-specificity phosphatases, which primarily catalyze the dephosphorylation of phosphatidylinositol (PI) phosphates. These lipids play critical roles in membrane trafficking, cytoskeletal organization, and cellular signaling. MTMR1 specifically targets phosphatidylinositol 3-phosphate (PI3P) and phosphatidylinositol 3.5-bisphosphate [PI(3.5)P2], modulating endosomal sorting, autophagy, and lysosomal function. Structurally, MTMR1 contains a conserved active phosphatase domain, a lipid-binding GRAM domain, and a coiled-coil region implicated in protein-protein interactions and subcellular localization.
Though less studied than some family members (e.g., MTM1 linked to X-linked myotubular myopathy), MTMR1 is thought to act redundantly or synergistically with other myotubularins to regulate phosphoinositide homeostasis. Dysregulation of MTMR1 has been associated with neurodevelopmental disorders and cancer, though its precise pathogenic mechanisms remain unclear. Recombinant MTMR1 protein, typically produced in bacterial or eukaryotic expression systems, enables biochemical studies (e.g., substrate specificity assays) and structural analyses to probe its enzymatic activity and regulatory interactions. Such research aids in deciphering its physiological roles and potential therapeutic relevance in lipid metabolism-related diseases.
