What is calmodulin, and what role does it play in signal transduction? What will be an ideal response?


Calmodium is an important Ca+2 binding protein. When calcium gates open in the plasma membrane
or the cytoplasm, the Ca+2 concentration rises in the cytosol. When calcium ions bind to a calmodium
molecule, the molecule changes shape and activates certain enzymes including protein kinases and
phosphatases
