Calspermin is a Testis Specific Calmodulin-Binding Protein Closely Related to Ca2+/Calmodulin-Dependent Protein Kinases
Calmodulin regulates a wide variety of cellular functions by interacting with its binding proteins or enzymes 1. Based on studies with a number of naturally occuring peptides that bind calmodulin with high affinity, it has been predicted that both ionic and hydrophobic interactions are involved in the association and that a general characteristic of a calmodulin-binding peptide is the ability to form a basic, amphiphilic helix 2–5. Indeed as the sequence of calmodulin-binding proteins have become known, the basic, amphiphilic helix has been shown to be the one common feature of the calmodulin-binding domain 6–16.
