Cat. No: GM-C38752 Product: H_GLP1R β-Arrestin Reporter CHO-K1 Cell Line The GLP-1 receptor (GLP-1R) is a G protein-coupled receptor encoded by the GLP1R gene on chromosome 6. It is expressed in pancreatic cells and brain neurons, playing a key role in insulin synthesis, secretion, and appetite regulation. GLP-1R activation increases intracellular cAMP levels via the adenylyl cyclase (AC) pathway, activating protein kinase A (PKA). This makes GLP-1R a critical target for diabetes drugs (GLP-1R agonists). Upon agonist activation, GPCRs are phosphorylated by GRKs, exposing β-arrestin binding sites. β-arrestin binds to the receptor and cell membrane, where it stabilizes and facilitates receptor trafficking to clathrin-coated pits (CCPs) for endocytosis. This process not only desensitizes GPCRs but also activates β-arrestin-mediated, non-G protein signaling pathways. H_GLP1R β-Arrestin Reporter CHO-K1 Cell Line is a clonal stable CHO cell line constructed using lentiviral technology, constitutive expression of the GLP1R receptor gene,and detected using enzyme fragment complementation (EFC) technology. When the agonist binds to the ligand, the two luciferase fragments complement each other to form an active complex. Upon addition of a luciferase substrate, the complex catalyzes the reaction to produce a detectable luminescent signal. This highly sensitive method enables real-time monitoring of receptor interactions as well as functional changes in the cellular environment, making it a powerful tool for drug screening and biological research. | ![]() |
