Hereditary myopathies (HM) are inherited disorders primarily affectin skeletal muscle tissue . HM are caused by mutations in different genes that encode proteins important for muscle structure and function. Mutations in dynamin-2, an ubiquitously expressed large GTP-ase implicated in several cellular processes including membrane trafficking and actin cytoskeleton dynamics, are linked to Centronuclear Myopathy (CNM) one of the most prevalent HM. Although the last two decades there has been much advanced in understanding how CNM-causing mutations affect dynamin-2 function in vitro, little is known about the impact of these mutations in dynamin-2 function in the tissues where it is expressed. My current research is focused in to understand how CNM-linked mutations affect dynamin-2 function in membrane trafficking and actin remodeling in skeletal muscles and central nervous system using animal models of the disease.
