WebThe results demonstrate that GPR15 internalisation is moderately dependent on GRKs and clathrin, and highly dependent on caveolin and dynamin. Moreover, a bystander arrestin recruitment assay showed that GPR15 recruits arrestin-3 to the cell membrane upon agonist stimulation, although GPR15 internalizes in an arrestin-independent manner.
