The Higgs laboratory is interested in the many ways mammalian cells use actin filaments. By its count, actin filaments are crucial to at least 20 distinct cellular processes in mammals, and it is certain there are more processes to be found (in fact, the lab has found some!). All of these structures use the same helical actin filaments, but often organize these filaments into very different higher order assemblies to conduct their specific functions. The actin monomers for all of these structures come from a common cytosolic pool, and are dynamically cycling between structures.
