BellBrook’s RGScreen assay is the only HTS -ready assay method for measuring Regulaor of G Protein Signaling (RGS) protein catalytic activity. The most direct way to detect RGS function is by measuring the increased GTPase activity of the associated Galpha protein. However, the GTPase activity of isolated Galpha proteins is limited by GDP dissociation, so RGS GAP activity cannot be measured using simple biochemical assays. Bellbrook’s novel RGScreen™ platform overcomes this kinetic constraint by using proprietary Galpha protein variants with altered GTP hydrolysis and GDP dissociation rates that enable detection of RGS GAP activity using the Transcreener® GDP Assay.
