NCIt definition : Cysteinyl leukotriene receptor 1 (337 aa, 39 kDa) is encoded by the human CYSLTR1
gene. This protein plays a role in leukotriene binding and downstream signaling that
regulates eosinophil migration and the proliferation and contraction of bronchial
smooth muscle cells.;
NCIt note : Cysteinyl leukotriene receptor 1 ligands include the cysteinyl leukotrienes (in order
of lowest to highest binding affinity): LTB4, LTC4, LTE4 and LTD4.;
