### CYP4X1 Gene Overview

**Gene Symbol:** CYP4X1  
**Location:** Chromosome 1  
**Gene Family:** Cytochrome P450 superfamily  

**Function:**  
The CYP4X1 gene encodes a cytochrome P450 enzyme that primarily functions as a monooxygenase. It plays a role in the metabolism of lipids and possibly in the regulation of neurovascular functions in the brain. The protein encoded by CYP4X1 selectively catalyzes the epoxidation of certain fatty acids, specifically the arachidonoyl moiety of anandamide, a key endocannabinoid. Unlike many other members of the cytochrome P450 family, CYP4X1 does not have significant hydroxylase activity toward various fatty acids, steroids, or prostaglandins.

**Mechanism of Action:**  
CYP4X1 utilizes molecular oxygen to perform its enzymatic function, inserting one oxygen atom into the substrate while reducing the other into water. This reaction is dependent on two electrons provided by NADPH through cytochrome P450 reductase (CPR).

### Additional Information

1. **Associated Genes:**
   - While specific associated genes may not be detailed in the initial summaries, cytochrome P450 genes often interact or have pathways overlapping with other members of the cytochrome P450 superfamily, including CYP4A, CYP2C, and CYP2D families.

2. **Aging and Age-Related Diseases:**
   - There is limited direct evidence linking CYP4X1 to aging or age-related diseases. However, dysfunction in cytochrome P450 enzymes is commonly implicated in the altered metabolism of drugs and hormones as organisms age, potentially impacting processes like inflammation and cardiovascular health. Studies on rats suggest there may be neuroprotective roles of CYP4X1 that could be relevant in age-related neurodegenerative conditions.

3. **Drug Interactions:**
   - While specific drugs directly interacting with CYP4X1 are not widely characterized in the literature, CYP enzymes are critical in drug metabolism, and potential drug interactions could arise from varying expressions of CYP4X1 in different tissues. Some drugs metabolized by related CYP isoforms may have indirect interactions or effects that could implicate CYP4X1's role in their metabolism.
   - Additionally, drugs or compounds influencing the endocannabinoid system may be indirectly related to CYP4X1’s activity since it modulates anandamide metabolism.

4. **Pathways and Biological Processes:**
   - **Endocannabinoid signaling**: Involved in the metabolism of anandamide, thus affecting signaling pathways regulated by cannabinoid receptors.
   - **Lipid metabolism**: Functionally linked to the metabolism of fatty acids and other lipids.
   - **Vascular function**: Suggestive roles in neurovascular health and possibly influencing pathways related to brain blood flow and neuroinflammation.

### Conclusion
CYP4X1 is a specialized member of the cytochrome P450 superfamily with a distinct functional role in endocannabinoid metabolism and potential implications in neurovascular function. Its influences on aging and pharmacology via drug metabolism pathways warrant further research to fully elucidate its biological significance.
