S1PR4
The s1pr4 Gene: Unraveling its Role in Health and Disease
Description
The s1pr4 gene encodes a protein called sphingosine-1-phosphate receptor 4, which is a crucial component of the immune system and plays a vital role in regulating a wide range of biological processes. This receptor interacts with a lipid molecule known as sphingosine-1-phosphate (S1P), which activates various signaling pathways within cells.
Associated Diseases
Mutations in the s1pr4 gene have been linked to several immunological disorders, including:
- Multiple sclerosis (MS): Characterized by inflammation and damage to the central nervous system, MS patients often have reduced S1P levels and impaired s1pr4 signaling.
- Rheumatoid arthritis (RA): An autoimmune disease that causes inflammation and joint pain, RA patients may have altered s1pr4 expression and S1P metabolism.
- Inflammatory bowel disease (IBD): A chronic condition involving inflammation of the digestive tract, IBD patients can exhibit abnormal s1pr4 expression and disrupted S1P signaling.
Did you Know ?
S1P, the ligand that activates s1pr4, has been shown to play a role in regulating vascular tone and lymphatic function. Studies have found that individuals with a single copy of a genetic variant in the s1pr4 gene have a 15% increased risk of developing pulmonary arterial hypertension, a condition characterized by high blood pressure in the lungs.
