Calcium-binding proteins have specific domains that bind to calcium and are known to be heterogeneous. One of the functions of calcium binding proteins is to regulate the amount of free (unbound) Ca 2+ in the cytosol of the cell. [1] The cellular regulation of calcium is known as calcium homeostasis.
Calmodulin I, abbreviated CALM1, is located on chromosome 14 of the human genome, and is one of the three isoforms of calmodulin. It’s found in all human tissues, although the expression varies depending on tissue type. There are high expression levels found in the brain, muscle, and blood.
The protein encoded by this gene is a member of the calcium-binding protein superfamily that includes calmodulin and troponin C. Originally described as a 27 kDa protein, it is now known to be a 28 kDa protein. It contains four active calcium-binding domains, and has two modified domains that are thought to have lost their calcium binding ...
Calmodulin is a small, highly conserved protein that is 148 amino acids long (16.7 kDa). The protein has two approximately symmetrical globular domains (the N- and C- domains) each containing a pair of EF hand motifs [5] separated by a flexible linker region for a total of four Ca 2+ binding sites, two in each globular domain.

Point mutations can occur in troponin C inducing alterations to Ca 2+ and Mg 2+ binding and protein structure, [1] leading to abnormalities in muscle contraction. [2] [3] In cardiac muscle, they are related to dilated cardiomyopathy (DCM) and hypertrophic cardiomyopathy (HCM). These known point mutations are: A8V; D145E; A31S; C84Y; E134D; Y5H ...
Calcium binding protein 1 is a protein that in humans is encoded by the CABP1 gene. [5] Calcium-binding protein 1 is a calcium-binding protein [6] discovered in 1999. [7] It has two EF hand motifs and is expressed in neuronal cells in such areas as hippocampus, habenular nucleus of the epithalamus, Purkinje cell layer of the cerebellum, and the amacrine cells and cone bipolar cells of the retina.
To change Ca 2+ levels in the cytosol, it can be actively pumped out of the cell (from the cytosol to the extracellular space), into the endoplasmic reticulum (ER), and into the mitochondria. Signaling occurs when the cell is stimulated to release Ca 2+ ions from intracellular stores, and/or when Ca 2+ enters the cell through plasma membrane ...
