  • It is created by combining GFP, calmodulin, and M13.

    • GFP emits light.
    • Calmodulin binds to calcium.

  • Default state:

    • M13 is attached to the right side.
    • GFP does not emit light.
    • 

  • When calcium binds to calmodulin,

    • The position of M13 changes.
    • As a result, the GFP emits light due to the structural change.
    • 
• The joy of using GFP.
