Lysophosphatidic Acid Receptor 1 Ct (EDG-2) Antibody – Rabbit Polyclonal

The integral membrane protein encoded by this gene is a lysophosphatidic acid (LPA) receptor from a group known as EDG receptors. These receptors are members of the G protein-coupled receptor superfamily. Utilized by LPA for cell signaling, EDG receptors mediate diverse biologic functions, including proliferation, platelet aggregation, smooth muscle contraction, inhibition of neuroblastoma cell differentiation, chemotaxis, and tumor cell invasion. Two transcript variants encoding the same protein have been identified for this gene [provided by RefSeq, Jul 2008]

Function: Receptor for lysophosphatidic acid (LPA), a mediator of diverse cellular activities. Seems to be coupled to the G(i)/G(o), G12/G13, and G(q) families of heteromeric G proteins. Stimulates phospholipase C (PLC) activity in a manner that is dependent on RALA activation. Ref.6

Subunit structure: Interacts with RALA and ADRBK1. Ref.6

Subcellular location: Cell surface. Cell membrane; Multi-pass membrane protein. Note: Prior to LPA treatment found predominantly at the cell surface but in the presence of LPA co-localizes with RALA in the endocytic vesicles. Ref.6

Tissue specificity: Expressed in many adult organs, including brain, heart, colon, small intestine, placenta, prostate, ovary, pancreas, testes, spleen, skeletal muscle, and kidney. Little or no expression in liver, lung, thymus, or peripheral blood leukocytes.

Sequence similarities: Belongs to the G-protein coupled receptor 1 family.
