Cysteinyl leukotriene receptor 1 (CYSLTR1) is a G protein-coupled receptor (GPCR) that plays a critical role in mediating inflammatory responses. It binds cysteinyl leukotrienes (CysLTs), lipid mediators derived from arachidonic acid metabolism, including LTC4. LTD4. and LTE4. These molecules are implicated in bronchoconstriction, vascular permeability, and immune cell recruitment, making CYSLTR1 a key target in asthma, allergic rhinitis, and other inflammatory disorders. The receptor signals primarily through Gq and Gi/o proteins, activating pathways such as phospholipase C (PLC)-IP3 and MAP kinase cascades.
Recombinant CYSLTR1 protein is engineered for in vitro studies to elucidate its structure-function relationships, ligand interactions, and signaling mechanisms. Typically produced in mammalian expression systems (e.g., HEK293 or CHO cells), the recombinant protein retains post-translational modifications essential for ligand binding and receptor activity. It is often tagged with fluorescent or affinity markers (e.g., His-tag, FLAG) to facilitate purification and detection. Researchers use this tool to screen antagonists (e.g., montelukast, a asthma drug), characterize mutations affecting receptor activity, or develop antibodies. Its study also extends to cancer research, as CysLT signaling may influence tumor progression. The availability of recombinant CYSLTR1 accelerates drug discovery and mechanistic studies, bridging gaps between cellular models and therapeutic applications.
