The assembly and disassembly of filaments of this globular protein is regulated by gelsolin, which modifies the viscous behavior of the cell. Vinculins anchor this intracellular protein at tight junctions. In pseudopods, the formation of fibers made of this protein initially propels the pseudopod forward. This is the smaller of two proteins that contracts to form the cleavage furrow during cytokinesis. In one structure, this protein is absent from the H-zone. Also in that structure, which is the sarcomere, troponin is attached to this protein, which makes up the thin fiber, and prevents it from binding to myosin. For 10 points, name this ubiquitous protein that makes up microfilaments.
