Overlapping homologous superfamilies
- Proton-dependent oligopeptide transporter family (IPR000109)
- Peptide transporter 3 (IPR031124)
This is a family of oligopeptide transporters nematodes (round worms) which includes oligopeptide transporter 3 (OPT3) from Caenorhabditis elegans. OPT3 can mediate the H+-coupled transport of peptides, but functions mainly as a H(+) channel. It is expressed exclusively in neurons. OPT3 probably plays an important role in the maintenance of H(+) homeostasis and in the clearance of peptides arising from neuropeptide metabolism [PMID: 10734106].
