Cysteinyl leukotriene receptor 1 is a protein that in humans is encoded by the CYSLTR1 gene.The cysteinyl leukotrienes LTC4 LTD4 and LTE4 are important mediators of human bronchial asthma. Pharmacologic studies have determined that cysteinyl leukotrienes activate at least 2 receptors the protein encoded by this gene and CYSLTR2. This encoded receptor is a member of the superfamily of G protein-coupled receptors and uses a phosphatidylinositol-calcium second messenger system.
