The first step in the primary chemical pathway for muscle contraction is for calcium in the muscle cell to combine with calmodulin. Then, the calcium/calmodulin complex "activates" a protein ...

We also show that both sarcomere organization and myosin light chain 2v phosphorylation are dependent on the activation of Ca2+/calmodulin pathway, a known activator of myosin light chain kinase.
