Small RhoGTPases regulate changes in post-synaptic spine morphology and density that support learning and memory. They are also major targets of synaptic disorders, including Autism. Here we sought to determine whether upstream RhoGTPase regulators,

ROCK1 forms the stable actomyosin filament bundles that initiate front–back and dendritic spine polarity, while ROCK2 regulates contractile force, Rac1 activity, and cofilin-mediated actin remodeling at the leading edge of migratory cells and the s

We have found that MLC-dependent activation of myosin IIB in migrating cells is required to form an extended rear, which coincides with increased directional migration. Activated myosin IIB localizes prominently at the cell rear and produces large, s

Using two-colour imaging and high resolution TIRF microscopy, we investigated the assembly and maturation of nascent adhesions in migrating cells. We show that nascent adhesions assemble and are stable within the lamellipodium. The assembly is indepe

We have used isoform-specific RNA interference knockdowns to investigate the roles of myosin IIA (MIIA) and MIIB in the component processes that drive cell migration. Both isoforms reside outside of protrusions and act at a distance to regulate cell

Cell migration is a complex, highly regulated process that involves the continuous formation and disassembly of adhesions (adhesion turnover). Adhesion formation takes place at the leading edge of protrusions, whereas disassembly occurs both at the c

Dendritic spines are micron-sized protrusions that constitute the primary post-synaptic sites of excitatory neurotransmission in the brain. Spines mature from a filopodia-like protrusion into a mushroom-shaped morphology with a post-synaptic density

Myosin IIA and IIB synergistically generate front–back polarity through their effects on actomyosin bundling formation and stability, and adhesion maturation, which are mediated by localized Rac GEF depletion.
