Despite recent progress in understanding lamellipodia extension, the molecular mechanisms regulating filopodia formation remain largely unknown. Myo10 is a MyTH4-FERM myosin that localizes to the tips of filopodia and is hypothesized to function in filopodia formation. To determine whether endogenous Myo10 is required for filopodia formation, we have used(More)
Endothelial cell migration is an important step during angiogenesis, and its dysregulation contributes to aberrant neovascularization. The bone morphogenetic proteins (BMPs) are potent stimulators of cell migration and angiogenesis. Using microarray analyses, we find that myosin-X (Myo10) is a BMP target gene. In endothelial cells, BMP6-induced Myo10(More)
Viruses exploit the cytoskeleton of host cells to transport their components and spread to neighbouring cells. Here we show that the actin cytoskeleton is involved in the release of Marburgvirus (MARV) particles. We found that peripherally located nucleocapsids and envelope precursors of MARV are located either at the tip or at the side of filopodial actin(More)
The intracellular pathogen Shigella flexneri forms membrane protrusions to spread from cell to cell. As protrusions form, myosin-X (Myo10) localizes to Shigella. Electron micrographs of immunogold-labelled Shigella-infected HeLa cells reveal that Myo10 concentrates at the bases and along the sides of bacteria within membrane protrusions.

APARNA BHASKAR BOHIL: Myosin-X is a molecular motor central to filopodia formation, adhesion and signaling (Under the direction of Dr. Richard E. Cheney) Understanding cellular and molecular components of cell migration is critical to the advancement of normal physiology and cancer biology. There is growing realization that finger-like cellular protrusions(More)
