The very strong CAG promoter contains the start of a gene encoding this protein in chickens.
The very strong CAG promoter contains the start of a gene encoding this protein in chickens. This 43-kilodalton protein and GAPDH are the most common loading controls for Western blots. This protein is stained red by phalloidin, and is regulated by the Rho GTPase family. Two critical concentrations of this protein determine if it polymerizes at the (*) barbed end, the pointed end, or both. At the cellular leading edge, it forms lamellipodia, and it can also bundle together to make stress fibers. A form this protein labelled F is formed by ATP hydrolysis and makes up a smaller component of the cytoskeleton than microtubules. For 10 points, name this protein found in microfilaments and separates myosin bands in sarcomeres.
