For 10 points, name this protein that make up sarcomeres along with myosin.
This protein is bound by fascin in microspikes, and this protein binds to the cytoplasmic faces of catenins in cadherin junctions. Depolymerization of this protein is prevented by phalloidin. By catalyzing exchange of ADP for ATP on this protein, Profilin promotes its polymerization. Polymerization of this protein at (*) lamellipodia allows cells to move. This protein is found in contractile rings that allow for cell division. This protein which, along with intermediate filaments and microtubules, makes up the cytoskeleton, and thin filaments are polymers of this protein.
