Agonist-promoted trafficking of human bradykinin receptors : Arrestin- and dynamin-independent sequestration of the B2 receptor and bradykinin in HEK293 cells
In this study, we analysed the agonist-promoted trafficking of human B2 (B2R) and B1(B1R) bradykinin (BK) receptors using wild-type and green fluorescent protein (GFP)-tagged receptors in HEK293 cells. B2R was sequestered to a major extent upon exposure to BK, as determined by the loss of cell-surface B2R using radioligand binding and by imaging of B2R-GFP using laser-scanning confocal fluorescenc
