TMEM16F, a member of the transmembrane protein 16 (TMEM16) family, is a calcium-activated ion channel and phospholipid scramblase critical for maintaining cellular membrane asymmetry. Discovered in 2010. it plays dual roles: facilitating ion transport (e.g., chloride) and scrambling phospholipids between membrane leaflets. This activity is essential for processes like blood coagulation, apoptosis, and cell-cell signaling. Structurally, it forms a dimer with each subunit containing 10 transmembrane domains and a hydrophilic groove for lipid scrambling.
TMEM16F is widely expressed in platelets, immune cells, and epithelial tissues. Its dysfunction links to Scott syndrome, a rare bleeding disorder caused by impaired phosphatidylserine exposure, crucial for clotting. Additionally, TMEM16F mediates extracellular vesicle release (e.g., microparticles in inflammation) and impacts viral entry (e.g., SARS-CoV-2). Recent studies highlight its role in neurodegenerative diseases, cancer metastasis, and osteogenesis, though mechanistic details remain debated.
As a therapeutic target, TMEM16F modulation holds potential for treating thrombosis, immune disorders, and neurological conditions. However, challenges persist in distinguishing its ion channel vs. scramblase functions and identifying selective inhibitors. Ongoing research aims to unravel its regulation by calcium, membrane tension, and lipid composition, offering insights into membrane dynamics and disease pathogenesis.
