Description

Lysophosphatidic acid receptor 1 (LPAR1), also designated EDG2, functions as a G protein-coupled receptor that mediates diverse cellular responses to lysophosphatidic acid signaling. This receptor plays critical roles in cell proliferation, survival, and migration, making it a compelling target for researchers investigating cancer progression, cardiovascular biology, and metabolic regulation. LPAR1 signaling pathways have emerged as particularly relevant in understanding tumor microenvironment dynamics and fibrotic disease mechanisms.

This recombinant monoclonal antibody, clone 4C3, offers the reproducibility and consistency that demanding experimental workflows require. Produced using recombinant technology in rabbit host, the antibody provides sequence-defined specificity against a synthetic peptide derived from human LPAR1. Unlike traditional hybridoma-derived antibodies, this recombinant format ensures lot-to-lot consistency, allowing you to maintain confidence in your results across extended studies and collaborative projects.

The antibody has been validated for Western blot applications, where it successfully detects LPAR1 at the predicted molecular weight of 42 kDa. Testing in HeLa and A375 whole cell lysates demonstrates reliable performance across different human cell line contexts, with recommended working dilutions ranging from 1:500 to 1:5000 providing flexibility to optimize signal intensity for your specific experimental conditions. The antibody is also validated for ELISA applications, expanding its utility across different detection platforms.

Supplied in a stabilized liquid format with glycerol for long-term storage stability, this affinity-purified antibody is well-suited for researchers exploring LPAR1 biology in signal transduction studies, cancer research, and cardiovascular investigations where consistent, reliable target detection is essential for meaningful experimental outcomes.

Target Background

Function(From Uniprot)

Receptor for lysophosphatidic acid (LPA). Plays a role in the reorganization of the actin cytoskeleton, cell migration, differentiation and proliferation, and thereby contributes to the responses to tissue damage and infectious agents. Activates downstream signaling cascades via the G(i)/G(o), G(12)/G(13), and G(q) families of heteromeric G proteins. Signaling inhibits adenylyl cyclase activity and decreases cellular cAMP levels. Signaling triggers an increase of cytoplasmic Ca(2+) levels. Activates RALA; this leads to the activation of phospholipase C (PLC) and the formation of inositol 1,4,5-trisphosphate. Signaling mediates activation of down-stream MAP kinases. Contributes to the regulation of cell shape. Promotes Rho-dependent reorganization of the actin cytoskeleton in neuronal cells and neurite retraction. Promotes the activation of Rho and the formation of actin stress fibers. Promotes formation of lamellipodia at the leading edge of migrating cells via activation of RAC1. Through its function as lysophosphatidic acid receptor, plays a role in chemotaxis and cell migration, including responses to injury and wounding. Plays a role in triggering inflammation in response to bacterial lipopolysaccharide (LPS) via its interaction with CD14. Promotes cell proliferation in response to lysophosphatidic acid. Required for normal skeleton development. May play a role in osteoblast differentiation. Required for normal brain development. Required for normal proliferation, survival and maturation of newly formed neurons in the adult dentate gyrus. Plays a role in pain perception and in the initiation of neuropathic pain.
