Substrates of the human oligopeptide transporter hPEPT2.
Oligopeptide transporters serve important functions in nutrition and pharmacology. In particular, these transporters help maintain the homeostasis of peptides. The peptide-transporter PEPT2 is a high-affinity and low-capacity type oligopeptide transporter from the proton-coupled oligopeptide transporter family. PEPT2 has recently received attention because of its potential application in target...
متن کاملHuman organic anion transporter 1 mediates cellular uptake of cysteine-S conjugates of inorganic mercury.
BACKGROUND The epithelial cells lining the renal proximal tubule have been shown to be the primary cellular targets where mercuric ions gain entry, accumulate, and induce pathologic effects in vivo. Recent data have implicated at least one of the organic anion transport systems in the basolateral uptake of inorganic mercury (Hg(2+)). METHODS Using a line of Madin-Darby canine kidney (MDCK) II...
متن کاملLocalization of PEPT1 and PEPT2 proton-coupled oligopeptide transporter mRNA and protein in rat kidney.
To determine the renal localization of oligopeptide transporters, Northern blot analyses were performed and polyclonal antisera were generated against PEPT1 and PEPT2, the two cloned rat H+/peptide transporters. Under high-stringency conditions, a 3.0-kb mRNA transcript of rat PEPT1 was expressed primarily in superficial cortex, whereas a 3.5-kb mRNA transcript of PEPT2 was expressed primarily ...
متن کاملMutation in an adaptor protein PDZK1 affects transport activity of organic cation transporter OCTNs and oligopeptide transporter PEPT2.
Genetic polymorphisms in xenobiotic transporters have recently been clarified to be associated with change in drug distribution and disposition. To expand on recent identification of direct interaction and functional regulation of several transporters by a PDZ (PSD95, Dlg and ZO1) domain containing protein PDZK1, the effect of mutation in PDZK1 on transport activity and subcellular localization...
متن کاملHuman copper transporter 2 is localized in late endosomes and lysosomes and facilitates cellular copper uptake.
High-affinity cellular copper uptake is mediated by the CTR (copper transporter) 1 family of proteins. The highly homologous hCTR (human CTR) 2 protein has been identified, but its function in copper uptake is currently unknown. To characterize the role of hCTR2 in copper homoeostasis, epitope-tagged hCTR2 was transiently expressed in different cell lines. hCTR2-vsvG (vesicular-stomatitis-virus...
