Calmodulin

thingiverse

Calmodulin (CaM) is an abbreviation for CALcium-MODULated proteIN, which represents its primary role as a calcium-binding messenger protein present throughout all eukaryotic cells. Calmodulin functions as a multifunctional intermediate messenger that converts calcium signals by binding to calcium ions and then modifies its interactions with numerous target proteins, conveying important information throughout the cell. The three-dimensional structure of mammalian Calmodulin is visualized in detail through a Protein Data Bank entry 3CLN. This image was generated using advanced software tools, allowing users to closely examine the intricate mechanisms of this essential protein. Representations are available as guides for manually coloring the molecule, highlighting various aspects such as the presence of calcium ions depicted in vibrant red spheres. A precise STL file has been created employing VMD technology. The visualizations showcase a clear protein backbone and detailed calcium-binding residues accompanied by nearby water molecules.
