背景信息

**Background of Recombinant Human MTMR3 Protein**

Myotubularin-related protein 3 (MTMR3) is a member of the myotubularin family, which comprises lipid phosphatases that regulate phosphoinositide metabolism by dephosphorylating phosphatidylinositol 3-phosphate (PI3P) and phosphatidylinositol 3.5-bisphosphate [PI(3.5)P2]. These lipids play critical roles in membrane trafficking, autophagy, and cellular signaling. MTMR3 contains a conserved phosphatase domain, a PH-GRAM domain for membrane binding, and a coiled-coil region mediating protein interactions. Unlike some family members, MTMR3 lacks intrinsic phosphatase activity but functions as a regulatory subunit, partnering with active phosphatases like MTMR2 to modulate enzymatic efficiency and substrate specificity.

Recombinant MTMR3 is typically produced in heterologous systems (e.g., bacterial or mammalian cells) for functional studies. Research highlights its involvement in autophagosome maturation, endosomal sorting, and receptor signaling. Dysregulation of MTMR3 is linked to neurodegenerative diseases, cancers, and Charcot-Marie-Tooth neuropathy, underscoring its role in maintaining cellular homeostasis. Recent studies also implicate MTMR3 in immune responses and viral infection pathways, making it a potential therapeutic target. Its recombinant form enables exploration of structure-function relationships and molecular mechanisms underlying these processes.
