Fig. 5From: QR code model: a new possibility for GPCR phosphorylation recognitionQR code model for GPCR phosphorylation recognition. Schematic diagram of the QR code model: ligands, GPCR type, GRK, arrestin, GPCR phosphorylation sites and other factors work together to determine the fate of phosphorylated receptor desensitization, endocytosis, the continuation of signal transmission, or other functionsBack to article page
