Product Description
Sphingosine 1-phosphate receptor 1 (S1P1) is a G protein-coupled receptor that specifically binds sphingosine 1-phosphate. It is primarily expressed on vascular endothelial cells, lymphocytes, and in the central nervous system. Its core function, mediated via Gi protein signaling, is to orchestrate the recirculation of lymphocytes from lymphoid organs into the bloodstream and to maintain vascular endothelial barrier integrity, serving as a critical gating molecule for immune cell trafficking. This receptor is the target of the multiple sclerosis drug fingolimod, which acts as a functional antagonist to inhibit lymphocyte egress, thereby exerting immunomodulatory effects.
Screeningbio’s CHO-K1/Rat S1P1 cell line overexpress rat S1PR1 and is designed to detect inhibition in intracellular cAMP levels in response to agonist stimulation of the receptor. Cisbio HTRF cAMP kit can be used to detect the signal.

Data
![CHO-K1/Rat S1P1 Agonist Assay. CHO-K1/Rat S1P1 cells were stimulated with 2.5 μM Forskolin and treated with reference agonist. The assay was run based on Revvity cAMP HTRF protocol. Non-linear regression was used to plot activity changes vs. [Compound, M], and EC50 values were determined, using GraphPad Prism software.](https://static.wixstatic.com/media/cbf7de_8a424c3087e74887b3d2d0963ee69b2b~mv2.png/v1/fill/w_75,h_75,al_c,q_85,usm_0.66_1.00_0.01,blur_2,enc_auto/cbf7de_8a424c3087e74887b3d2d0963ee69b2b~mv2.png)
