Leukotriene receptor

The leukotriene (LT) receptors are G protein-coupled receptors that bind and are activated by the leukotrienes. They include the following proteins:


 * Leukotriene B4 receptors (BLTRs) – bind to and are activated by LTB4:
 * BLT1 (Leukotriene B4 receptor 1) –
 * BLT2 (Leukotriene B4 receptor 2) –
 * Cysteinyl leukotriene receptors (CysLTRs) – bind to and are activated by LTC4, LTD4, and LTE4:
 * CysLT1 (Cysteinyl leukotriene receptor 1) –
 * CysLT2 (Cysteinyl leukotriene receptor 2) –

The recently elucidated CysLTE, represented by GPR99/OXGR1, may constitute a third CysLTR.
