Kalmoduliiniin

Kalmoduliiniin is a protein that plays a crucial role in cellular signaling. It is a small, highly conserved calcium-binding protein found in all eukaryotic cells. Kalmoduliiniin acts as a molecular switch, binding to calcium ions when their concentration rises within the cell. This binding causes a conformational change in the kalmoduliiniin molecule, enabling it to interact with and regulate the activity of a wide range of target proteins.

These target proteins are involved in numerous cellular processes, including muscle contraction, neurotransmitter release, gene expression, and cell cycle progression. By modulating the function of these proteins, kalmoduliiniin allows cells to respond to extracellular stimuli and internal changes. The precise cellular function of kalmoduliiniin is dependent on its localization within the cell and the specific target proteins it interacts with. Its ability to integrate calcium signals with diverse cellular responses makes it a central component of cellular communication networks. Dysregulation of kalmoduliiniin function has been implicated in various diseases, highlighting its importance in maintaining cellular homeostasis.
