'''LPAR5''' is a [[G protein-coupled receptor]] that belongs to the [[lysophosphatidic acid]] (LPA) receptor family. LPA receptors are critical for various biological functions, including cell proliferation, survival, and migration. LPAR5 specifically binds to lysophosphatidic acid, a lipid mediator with diverse physiological and pathological roles. This receptor is involved in several signaling pathways that regulate cellular processes such as cytoskeletal organization, ion channel activity, and hormone secretion.

LPAR5 mediates the biological activities of lysophosphatidic acid (LPA) at the cellular level. Upon binding to LPA, LPAR5 activates multiple downstream signaling cascades, including those involving [[phospholipase C]], [[protein kinase C]], and [[Rho GTPase]]s. These pathways contribute to various aspects of cell behavior, such as morphology changes, motility, and proliferation. LPAR5's role in these processes makes it a significant player in tissue homeostasis and repair, as well as in the development of diseases like cancer, fibrosis, and inflammation.
LPAR5 is activated by [[lysophosphatidic acid]] (LPA), a bioactive lipid that acts as a signaling molecule.
