Cellular motility requires rapid changes in the consistency
and organization of the peripheral cytoplasm. To produce outward protrusions
such as pseudopods and lamellipods, the actin cytoskeleton must be
continually remodeled in response to intracellular and external stimuli.
Our laboratory is applying a balanced
application of molecular and structural biology approaches as well as video
microscopy and microinjection to determine how Cap G, ABM complexes and profilin control actin assembly.
We are also exploring how anthrax toxins may
affect the changes in the actin cytoskeleton associated with cell motility.
Major research themes in our laboratory are:
