Mouse Lpar4(Lysophosphatidic acid receptor 4) ELISA Kit

Background

LPAR4 is a G protein-coupled receptor for lysophosphatidic acid (LPA) that preferentially couples to G12/13 and Gq proteins, influencing cytoskeletal organization, calcium signaling, and cell migration. LPAR4 is expressed in hematopoietic cells, endothelial cells, and certain epithelial tissues, where it regulates cell adhesion, proliferation, and vascular development. Unlike other LPA receptors, LPAR4 has been implicated in blood vessel stability and lymphocyte trafficking, playing a role in vascular homeostasis and immune cell regulation. LPAR4 activation contributes to endothelial barrier function and vascular remodeling, making it relevant in conditions such as vascular inflammation and atherosclerosis. In cancer, LPAR4’s role is less well characterized compared to other LPA receptors, but it has been linked to cell migration and metastasis in certain malignancies. Dysregulation of LPAR4 signaling is associated with vascular disorders and immune dysfunction. Targeting LPAR4 offers therapeutic potential for vascular diseases, immune modulation, and cancer progression, highlighting its emerging role in LPA-mediated signaling pathways.
