PathHunter® β-Arrestin Assays as a Universal Tool For Orphan GPCR.
Review the available cell-based assays covering >90% of the GPCRome for cAMP and calcium detection, GTPγS binding, β-arrestin recruitment, receptor internalization. Jun 01, 2016 · In this assay, β-arrestin activity is measured in live cells (DiscoveRx ® Pathunter ® cell lines) by using an enzyme complementation assay and a chemoluminescent readout (Fig. 1). The cell lines are overexpressing either the human CB 1 or CB 2 receptor, which are both tagged at the C-terminus by a ProLink™, i.e., a small fragment of β. Cells were stimulated with a dose-response of BI for 1.5 h (arrestin recruitment assay) or 3 h (internalization assay) at 37 °C and then lysed for 1 h in the dark in the presence of PathHunter Detection Reagent per the manufacturer's recommendations.

Characterizing cannabinoid CB2 receptor ligands using DiscoveRx PathHunter beta-arrestin assay Abstract The authors have characterized a set of cannabinoid CB (2) receptor ligands, including triaryl bis sulfone inverse agonists, in a cell-based receptor/beta-arrestin interaction assay (DiscoveRx PathHunter). 2.8 β-arrestin 2 recruitment assay. The ability of agonists in promoting FPRs to β-arrestin was evaluated in the PathHunter eXpress Chinese hamster ovary (CHO) cells-K1 FPR1 or FPR2 cells from DiscoverX (Fremont, CA, USA) which co-express ProLink tagged FPR1 or FPR2 and an enzyme acceptor tagged β-arrestin so that β-arrestin binding can be.
Why Study GPCR Arrestin Recruitment | Eurofins.
These assays generally require a cell line coexpressing a fluorophore-tagged GPCR of interest and a luciferase-tagged β-arrestin. Upon GPCR-β-arrestin interaction, a BRET (bioluminescence resonance energy transfer) signaling is generated by proximity of the two tags. Reporter gene-based assays for β-arrestin activity are also available. The PathHunter β-arrestin cell lines provided by DiscoveRx are listed in Supplementary Table S3. Human GPCRs were tagged by the incorporation of a short ProLink amino acid sequence from β-galactosidase within their C-terminus....

Background. CCR8 (C-C chemokine receptor type 8) is a receptor for the chemokines CCL1 (I-309). The receptor regulates monocyte chemotaxis and thymic cell line apoptosis, and is an additional alternative coreceptor with CD4 for HIV-1 infection. CCR8 plays a role on cell types of relevance to respiratory diseases such as asthma, chronic.
