Extended Data Fig. 6: Surface expression of GPR161 mutants.

a) Representative flow cytometry surface expression histograms for receptors and mutants used in cell-based assays. b) Surface expression of receptors and mutants quantified by anti-FLAG-A647 median fluorescence intensity ± sd from n = 3 (for L465PC-term) or n = 4 (for rest) biologically independent samples.
