Webb1 jan. 2024 · Definition. The proton-coupled oligopeptide transporters from the SLC15 family are integral membrane proteins that mediate the cellular uptake of dipeptides, tripeptides, and peptide-like (peptidomimetic) drugs (e.g., antiviral prodrugs). Substrate movement across the membrane is coupled with proton movement downward and … WebbVesicular transporters move neurotransmitters into synaptic vesicles, regulating the concentrations of substances within them.
