WebJul 4, 2024 · Calmodulin, or calcium-modulated protein, is a calcium-binding protein found in the cytoplasm of all eukaryotic cells. It interacts with many other proteins in the cell, and acts as a regulator or an effector molecule in a wide variety of cellular functions. These functions include things as diverse as regulation of the cell cycle ...
