(C) BRET between Rab4-Venus and CaSR-Nluc-WT, with vehicle (DMSO) or Dyngo-4a. N = 5. (D) SIM of SNAP-CaSR-647 and Venus-Rab4. Scale, 5 μm. Arrows show colocalization. N = 23 (0 mM), N = 22 (3 mM) from N = 4 biological replicates. (E) SIM images of cells exposed to FLAG antibody and either non-permeabilized (total) or exposed to 0 or 3 mM Ca 2+ e for 30 min or 30 min with 3-h recovery, before acid strip to remove cell surface FLAG.
