LT4R1 rabbit pAb - 100 μL

Function: Receptor for extracellular ATP > UTP and ADP. The activity of this receptor is mediated by G proteins which activate a phosphatidylinositol-calcium second messenger system. May be the cardiac P2Y receptor involved in the regulation of cardiac muscle contraction through modulation of L-type calcium currents. Is a receptor for leukotriene B4, a potent chemoattractant involved in inflammation and immune response. PTM: Phosphorylated by GRK6 upon leukotriene B4 binding; which promotes desensitization. similarity: Belongs to the G-protein coupled receptor 1 family. tissue specificity: Expressed at highest levels in heart, skeletal muscle and at lower levels in brain and liver. High level of expression in lymphoid tissues.
