The discovery made by Vanesa Tomatis, a PhD student in Associate Professor Frederic Meunier’s laboratory, demonstrates how Myosin VI has the impressive ability to anchor secretory vesicles that are at least 5,000 times greater in size, near their release site.
“By tethering and anchoring secretory granules, Myosin VI helps to maintain an active pool of vesicles near the plasma membrane, which is key to sustaining communication between neuronal cells,” Associate Professor Meunier said.
Associate Professor Meunier and his team are now looking to better understand how the Myosin VI manages to grab and hold vesicles through the use of super resolution microscopy.
They hope the discovery will lead to new ways to reinstate or regulate neuronal communication in various brain disorders.
The paper was published in The Journal of Cell Biology on February 4 2013.
