### SEC14L4 Gene Summary

**Gene Symbol:** SEC14L4  
**Location:** Human chromosome 16q24.3

#### General Description
The SEC14L4 gene encodes a protein that is homologous to the yeast SEC14 gene, a well-established phosphatidylinositol transfer protein critical for the maturation and functioning of the Golgi apparatus. Although its specific biological functions in humans remain largely uncharacterized, it is inferred to play a role in lipid transport and possibly in the modulation of cellular signaling pathways through the transport of various hydrophobic ligands, such as tocopherol (vitamin E), squalene, and phospholipids.

#### 1. Associated Genes
While SEC14L4 may not have extensively characterized interaction data, several genes have been noted in studies focusing on lipid metabolism and intracellular transport systems that may interact indirectly with SEC14L4. Some of these include:

- **SEC14L3**: A close paralog involved in lipid transport.
- **ARL2** and **ARL3**: Genes involved in Golgi function and vesicle transport.
- **COPB1**: Associated with the Golgi-associated vesicle transport.
- **FBLN1**: Implicated in extracellular matrix function and might interact in lipid-related processes.

#### 2. Aging and Age-Related Diseases
The SEC14L4 gene has been suggested to have implications in aging and age-related diseases, although research is still developing:

- **Neurodegenerative Diseases**: Alterations in lipid metabolism are often associated with neurodegenerative conditions such as Alzheimer’s. SEC14L4 may play a role in maintaining lipid homeostasis, which is disrupted in aging and neurodegeneration.
- **Metabolic Disorders**: Given its role in lipid transfer, SEC14L4 could be involved in metabolic syndrome, which typically worsens with age. Biomolecular studies may reveal correlations with lipid profiles in older populations.

#### 3. Drug Interactions
Currently, there are no specific drugs explicitly known to interact with SEC14L4. However, due to its role in phospholipid and tocopherol transport, it may indirectly affect the efficacy of lipid-modulating drugs such as:

- **Statins**: Typically used for cholesterol management, which may interact with various lipid pathways.
- **Fibrates**: Medications that affect lipid metabolism may exhibit interactions at pathways where SEC14L4 participates.
- **Fat-soluble vitamins and supplements (like vitamin E)** might influence SEC14L4 function and its downstream effects.

#### 4. Pathways and Biological Processes
SEC14L4 is thought to participate in several critical biological processes:

- **Lipid Metabolism**: Involvement in the transport of hydrophobic ligands indicates a role in lipid anabolic pathways.
- **Golgi Organization**: Given its similarities to the yeast SEC14 protein, it may be implicated in the Golgi apparatus's biogenesis and function.
- **Signaling Pathways**: The transport of phosphoinositides and other lipid mediators suggests SEC14L4 could influence lipid-mediated signaling pathways vital for cellular responses.

#### Conclusion
In summary, the SEC14L4 gene appears to play a versatile role in lipid transport and Golgi apparatus functionality. While research remains ongoing, understanding its associations with aging and potential drug interactions could illuminate further insights into its biological importance and relevance to health conditions related to metabolism and neurodegeneration.
