| Post Translational Modifications | Maximal phosphorylation of Ser-336 correlates with maximal relaxation of aorta in response to acetylcholine. |
| Function | Plays a role in the regulation of contractile properties of both striated and smooth muscles. When unphosphorylated, may inhibit myosin dephosphorylation. Phosphorylation at Ser-299 reduces this inhibitory activity. |
