Other Information

**Key Characteristics** CNTN1 is a transmembrane protein with four immunoglobulin-like domains, which enable it to form homophilic or heterophilic interactions with other contactin family members. This protein is specifically expressed in neurons and neural precursors, where it plays a critical role in axon guidance, neuronal migration, and synaptogenesis. CNTN1 is also involved in the regulation of gene expression, particularly in the context of Notch signaling, which is a key pathway in neuronal development. **Pathways and Functions** CNTN1 is integral to several signaling pathways, including: 1. **Notch signaling pathway**: CNTN1 interacts with Notch1 and Notch2, which are key receptors in the Notch signaling pathway. This interaction transmits signals to the nucleus, regulating gene expression and neuronal development. 2. **Axon guidance**: CNTN1 is involved in the guidance of axons during neuronal development, where it interacts with other axonal guidance molecules, such as L1cam and neurofascin. 3. **Cell-cell adhesion**: CNTN1 mediates cell-cell adhesion, particularly between neurons and glial cells, which is essential for maintaining the integrity of the nervous system. 4. **Gene expression regulation**: CNTN1 regulates gene expression through its interaction with Notch signaling, which is critical for neuronal development and differentiation. **Clinical Significance** CNTN1 has been implicated in several neurological disorders, including: 1. **Autism spectrum disorder**: Studies have shown that mutations in CNTN1 are associated with autism spectrum disorder, highlighting its role in neuronal development and synaptic function. 2. **Schizophrenia**: CNTN1 has been implicated in schizophrenia, where it is thought to contribute to the disruption of normal neuronal function and connectivity. 3. **Neurodegenerative diseases**: CNTN1 has been implicated in neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease, where it is thought to contribute to the disruption of normal neuronal function and connectivity. In conclusion, CNTN1 is a critical protein involved in cell-cell adhesion, axon guidance, and gene expression regulation in the nervous system. Its dysregulation has been implicated in several neurological disorders, highlighting its importance in maintaining normal neuronal function and connectivity. Further research is needed to fully elucidate the role of CNTN1 in neurological disorders and to explore its potential as a therapeutic target. **Additional Considerations** * CNTN1 is also expressed in other tissues, including the immune system, where it may play a role in modulating immune responses. * The protein has been shown to interact with other molecules, such as L1cam and neurofascin, which are involved in axon guidance and neuronal development. * CNTN1 has been implicated in the regulation of sodium ion transport, which is critical for maintaining normal neuronal function. Overall, CNTN1 is a complex protein with multiple roles in the nervous system, and its dysregulation has significant implications for human health. Further research is needed to fully elucidate its role in neurological disorders and to explore its potential as a therapeutic target.

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.
