4 Lysophosphatidic acid (LPA) stimulates cells by activation of five G-protein-coupled receptors, termed LPA 1-5. lysophosphatidic acid lysophosphatidic acid receptor 1 Mus musculus
5 Lysophosphatidic acid (LPA) stimulates cells by activation of five G-protein-coupled receptors, termed LPA 1-5. lysophosphatidic acid lysophosphatidic acid receptor 1 Mus musculus
6 Agonist-dependent internalization of LPA 1, however, requires a cluster of serine residues (amino acids 341-347) located proximal to the dileucine motif, beta-arrestin, and to a lesser extent clathrin AP-2. Serine lysophosphatidic acid receptor 1 Mus musculus
7 Agonist-dependent internalization of LPA 1, however, requires a cluster of serine residues (amino acids 341-347) located proximal to the dileucine motif, beta-arrestin, and to a lesser extent clathrin AP-2. dileucine lysophosphatidic acid receptor 1 Mus musculus
8 The serine cluster of LPA 1 is required for beta-arrestin2-GFP translocation to the plasma membrane and signal desensitization. Serine lysophosphatidic acid receptor 1 Mus musculus
9 Evidence for the beta-arrestin independence of PMA-induced internalization of LPA 1 comes from the observations that beta-arrestin2-GFP is not recruited to the plasma membrane upon PMA treatment and that LPA 1 is readily internalized in beta-arrestin1/2 knock-out mouse embryonic fibroblasts.
