1 SUPPLEMETARY FIGURE LEGEDS Supplementary Fig. 1. Flow cytometric analysis of wildtype, mutant and chimeric protein surface expression. Cells transduced with the individual constructs indicated were stained for CD69 or KRp1A ectodomains, or Flag in the case of S1P-receptor constructs. Histogram overlays group constructs in accord with their appearance in Western blots in the designated figure. Dot plots show flow cytometric analysis of Flag-S1P 1 and CD69 on the indicated WEHI231 cell lines that correspond to the cells used for the binding studies in Figure 10. Supplementary Fig. 2. Point mutations of all residues in the HEGSI motif of CD69 to alanine. on-specific bands are indicated with an asterisk. Supplementary Fig. 3. A. Flow cytometric analysis of S1P 1 mutants with point mutations in helical segments co-transduced with CD69 and hkrp1a in WEHI231 cells. The cells are costained for CD69 and KRp1A ectodomains and the Flag-S1P receptors and mutants indicated. B. Co-IP of the mutants indicated. o mutant (P1 through P8) exhibited a more than 1.5 fold difference in HA/Flag signal by densitometry. The result is representative of two experiments. on-specific bands are indicated with an asterisk. Supplementary Fig. 4. Test of electrostatics of S1P 1 and S1P 3. Structure was generated with modeller using the most homologous GPCR structure (β1-adrenergic receptor, pdb ID 2VT4). The region of the GPCR represented by helix 4 is highlighted by a black oval. Other helices on this surface are annotated. 1
