Other Information

**Key Characteristics:** ALOX15B is a type B lipoxygenase enzyme that exhibits distinct substrate specificity, primarily catalyzing the conversion of arachidonic acid into 15-ETE. This enzyme is highly expressed in various tissues, including the lung, colon, skin, and brain, where it plays a crucial role in regulating immune responses and lipid metabolism. ALOX15B is also involved in the biosynthesis of other eicosanoids, such as lipoxins and hepoxilins, which have anti-inflammatory and pro-resolving properties. **Pathways and Functions:** ALOX15B is integral to several signaling pathways, including the endocannabinoid, cytokine, and chemokine pathways. The enzyme's activity is tightly regulated by various post-translational modifications, which control its substrate specificity and enzymatic activity. ALOX15B's functions can be broadly categorized into the following: 1. **Immune regulation:** ALOX15B produces 15-ETE, which has anti-inflammatory and pro-resolving properties, modulating immune responses in various tissues. 2. **Lipid metabolism:** The enzyme regulates the metabolism of arachidonic acid, a polyunsaturated fatty acid, into 15-ETE and other eicosanoids. 3. **Cell differentiation and proliferation:** ALOX15B influences cell differentiation, proliferation, and migration by regulating the expression of key transcription factors and growth factors. 4. **Cytoskeletal organization:** The enzyme's activity affects cytoskeletal organization and cell adhesion, influencing cellular processes such as migration and invasion. **Clinical Significance:** Dysregulation of ALOX15B has been implicated in various diseases, including: 1. **Asthma and COPD:** Altered expression of ALOX15B has been linked to airway inflammation and remodeling in asthma and COPD. 2. **Cancer:** The enzyme's activity has been associated with cancer progression, metastasis, and resistance to chemotherapy. 3. **Neurological disorders:** ALOX15B has been implicated in the pathogenesis of neurodegenerative diseases, such as Alzheimer's and Parkinson's. 4. **Cardiovascular disease:** The enzyme's activity has been linked to atherosclerosis and cardiovascular disease. In conclusion, ALOX15B is a critical regulator of lipid metabolism and immune responses, playing a pivotal role in various cellular processes. Understanding the mechanisms of ALOX15B's action and its clinical significance can provide valuable insights into the development of novel therapeutic strategies for diseases characterized by dysregulation of this enzyme.

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.
