This protein forms aggregates in Hirano bodies. This protein is imaged using fluorescentphalloidin, and in red blood cells it complexes with band 4.1 protein at the ends of spectrin.
This protein forms aggregates in Hirano bodies. This protein is imaged using fluorescentphalloidin, and in red blood cells it complexes with band 4.1 protein at the ends of spectrin. It bindsto catenins on the cytoplasmic side of adherens junctions. Upon binding to ATP, it switches from aglobular form to a more aggregation-prone form, which creates a helical string. This protein isresponsible for forming the mechanism that pinches cells apart in (*) cytokinesis, and it is alsoresponsible for extending pseudopods in amoebas. Polymers of this protein move closer together duringmuscle contraction, due to myosin attaching to this protein and pulling. For 10 points, name this proteinthat forms the thin filaments of the cytoskeleton.
