Other Information

**Key Characteristics:** 1. **Channel Type:** SK channels are small conductance calcium-activated potassium channels, which are characterized by their ability to respond to increases in intracellular calcium concentrations. 2. **Subcellular Localization:** These channels are primarily localized to the plasma membrane, where they regulate the flow of potassium ions in and out of the cell. 3. **Cellular Expression:** KCNN3 is widely expressed in various cell types, including retinal bipolar neurons, astrocytes, dopaminergic neurons, and endothelial cells. 4. **Protein Structure:** The KCNN3 protein consists of six transmembrane domains and two pore-forming domains, which facilitate the channel's function. **Pathways and Functions:** 1. **Neuronal Excitability:** SK channels modulate neuronal excitability by regulating the flow of potassium ions, which affects the action potential threshold and neuronal firing. 2. **Muscle Relaxation:** SK channels contribute to muscle relaxation by facilitating the efflux of potassium ions, which counteracts muscle contraction. 3. **Immune System Modulation:** SK channels play a role in regulating immune responses, particularly in the context of T-cell activation and cytokine production. 4. **Inflammation:** KCNN3 has been implicated in the regulation of inflammatory responses, including the production of pro-inflammatory cytokines. **Clinical Significance:** 1. **Neurological Disorders:** Abnormalities in SK channel function have been linked to various neurological disorders, including epilepsy, migraines, and Parkinson's disease. 2. **Immune System Dysregulation:** Dysregulation of SK channels has been implicated in autoimmune diseases, such as multiple sclerosis and rheumatoid arthritis. 3. **Cardiac Arrhythmias:** Alterations in SK channel function have been associated with cardiac arrhythmias, including atrial fibrillation and ventricular tachycardia. 4. **Pain Modulation:** SK channels have been shown to play a role in pain modulation, particularly in the context of neuropathic pain. In conclusion, the KCNN3 gene encodes for a critical component of the SK channel family, which regulates various cellular processes, including neuronal excitability, muscle relaxation, and immune system modulation. Understanding the roles of KCNN3 in these processes has significant implications for the treatment and management of neurological disorders, immune system dysregulation, and cardiac arrhythmias.

Database document:

This is a preview of the gene's schema. Only a few entries are kept for 'singleCellExpressions,' 'mRNAExpressions,' and other large data arrays for visualization purposes. You can zoom in with the mouse wheel for a closer view, and the text will adjust automatically if necessary. For the full schema, download it here.
