G Protein Dependent Functional Assays
Creative Biolabs provides G protein dependent functional assay services based on multiple assay formats to accelerate GPCR research and drug development. We can further help speed up your drug discovery by combining high-throughput technology.
Importance of G Protein Dependent Functional Assays
G proteins, also known as guanine nucleotide-binding proteins, typically exist in either an active GTP-bound state or an inactive GDP-bound state. G protein-coupled receptors (GPCRs), one of the most successful therapeutic targets, can activate heterotrimeric G proteins to elicit cellular responses. GPCR-G protein interactions are involved in signal transduction cascades and the modulation of downstream effector events.
Binding assays are helpful to identify new compounds targeting GPCRs. G protein dependent functional assays are essential for further analysis of G protein activation and G protein-mediated biological events, which can help to fully describe the overall characteristics of these compounds and provide useful information on the selection of candidate compounds.
