Do G protein-coupled receptors have signal sequences for expression at the cell surface?
4 answers
G protein-coupled receptors (GPCRs) do not possess classical signal sequences for expression at the cell surface. Instead, various methods have been developed to measure and quantify the cell surface expression of GPCRs. The diversity in GPCR signaling can arise from changes in receptor sequences, expression levels, and the generation of functionally diverse isoforms with distinct signaling properties. Techniques like live-cell radioligand binding assays and biosensors based on bioluminescence resonance energy transfer (BRET) have been developed to study GPCR activation and signaling pathways without the need for classical signal sequences. GPCRs play a crucial role in mediating extracellular signals and activating downstream effectors, making them prime pharmacological targets with significant implications for drug development and disease pathways.How is the phakgocytosis ability quantified using CFSE labeld thymocyte in mouse model?
