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. |7tm 1| |leukotriene B4 receptor activity| |leukotriene receptor activity| |leukotriene signaling pathway| |galanin receptor activity| |G protein-coupled peptide receptor activity| |nucleotide binding| |phospholipase C-activating G protein-coupled receptor signaling pathway| |neuropeptide signaling pathway| |membrane raft| |muscle contraction| |muscle system process| |inflammatory response| |G protein-coupled receptor signaling pathway| |defense response| |integral component of plasma membrane| |immune response| |system process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp145|PNU96415E 10μM R03 exp145]]|-1.71| |[[:results:exp459|Bleomycin 5μM R08 exp459]]|-1.7| |[[:results:exp68|Clomiphene 4.4μM R02 exp68]]|1.7| No correlation found to any other genes in chemogenomics.
