The Technology
Mitochondria play a central role in cellular metabolism, signaling, and cell survival, making them important targets for both therapeutic intervention and biological research. However, selectively delivering molecules to mitochondria within living cells remains a significant challenge.
This technology is based on short peptides derived from Myosin 19 (Myo19), a protein that naturally localizes to the outer mitochondrial membrane and regulates mitochondrial positioning and dynamics. These peptides act as highly specific mitochondrial targeting signals, enabling efficient and selective delivery of molecules to mitochondria.
The targeting sequence is derived from a defined region within Myo19 that directly anchors to the mitochondrial membrane, allowing precise localization without the need for complex delivery systems.
These peptides can be conjugated to a wide range of cargos—including fluorescent probes, biomolecules, and therapeutic agents—enabling both mitochondrial labeling and targeted delivery applications.
By leveraging a natural mitochondrial transport mechanism, this approach provides a simple, modular, and efficient strategy for mitochondrial targeting in living cells.
