Other Information

**Key Characteristics:** INSIG1 is a transcriptional regulator that belongs to the insulin-induced gene family. It is induced by insulin and is involved in the negative regulation of various metabolic pathways. The protein is primarily localized to the endoplasmic reticulum (ER) and is involved in the sequestration of cholesterol and oxysterols. INSIG1 interacts with SREBP, a transcription factor that regulates cholesterol synthesis and uptake, thereby modulating the activity of the SREBP pathway. **Pathways and Functions:** INSIG1 is involved in the following pathways: 1. **Cellular response to insulin stimulus:** INSIG1 is induced by insulin and plays a crucial role in modulating the insulin signaling pathway. 2. **Cholesterol biosynthetic process:** INSIG1 regulates the activity of SREBP, which is essential for cholesterol synthesis. 3. **Cholesterol homeostasis:** INSIG1 helps maintain cholesterol homeostasis by regulating the expression of genes involved in cholesterol synthesis and uptake. 4. **Metabolism of lipids and steroids:** INSIG1 is involved in the negative regulation of lipid and steroid biosynthesis. 5. **Protein secretion and exit from the ER:** INSIG1 regulates the secretion of proteins from the ER and their exit from the ER. 6. **SREBP signaling pathway:** INSIG1 interacts with SREBP, modulating its activity and regulating the expression of genes involved in cholesterol synthesis and uptake. **Clinical Significance:** Dysregulation of INSIG1 has been implicated in various diseases, including: 1. **Atherosclerosis:** INSIG1 plays a crucial role in maintaining cholesterol homeostasis, and its dysregulation can contribute to the development of atherosclerosis. 2. **Metabolic disorders:** INSIG1 is involved in the regulation of lipid and steroid biosynthesis, and its dysregulation can contribute to metabolic disorders, such as obesity and diabetes. 3. **Cancer:** INSIG1 has been implicated in the regulation of cell growth and differentiation, and its dysregulation can contribute to cancer development and progression. 4. **Neurological disorders:** INSIG1 is expressed in neurons and is involved in the regulation of cholesterol homeostasis, and its dysregulation can contribute to neurological disorders, such as Alzheimer's disease. In conclusion, INSIG1 is a critical regulator of cholesterol homeostasis and metabolic pathways. Its dysregulation can contribute to various diseases, highlighting the importance of understanding its mechanisms of action and its role in maintaining tissue homeostasis.

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.
