This molecule forms the A band of the sarcomere.
This protein consists of two identical heavy chains, two regulatory light chains, and two essential light chains. Each heavy chain contains an alpha helix in the neck region, which associates with the light chains, as well as a tail domain and a globular head domain. This molecule forms the A band of the sarcomere. When ATP is hydrolyzed, this protein's head changes shape and dissociates from an actin filament. For 10 points, name this protein that, along with actin, is responsible for the sliding-filament model of muscle contraction.
