Potential Test Question:
a. Describe the overall structure of
calmodulin. Diagram and describe in detail the structure and composition of one of calmodulin's Ca++-binding sites.
What conformation of calmodulin is promoted by Ca++ binding in the
presence of a target peptide?
b. What is the effect of increased production of IP3 (inositol-1,4,5-trisphosphate) within a cell? What processes contribute to the turning off of an IP3-activated Ca++ signal?
