CC -!- FUNCTION: Proton-coupled amino-acid transporter that transports
CC oligopeptides of 2 to 4 amino acids with a preference for dipeptides
CC (PubMed:11027540). Transports the dipeptide-like aminopeptidase
CC inhibitor bestatin (By similarity). Can also transport the
CC aminocephalosporin antibiotic cefadroxil (By similarity). Also able to
CC transport carnosine (By similarity). Involved in innate immunity by
CC promoting the detection of microbial pathogens by NOD-like receptors
CC (NLRs) (PubMed:29784761). Probably acts by mediating transport of
CC bacterial peptidoglycans across the plasma membrane: catalyzes the
CC transport of certain bacterial peptidoglycans, such as muramyl
CC dipeptide (MDP), the NOD2 ligand (PubMed:29784761).

CC stimulation (PubMed:29784761). {ECO:0000269|PubMed:29784761}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily. Proton-
CC dependent oligopeptide transporter (POT/PTR) (TC 2.A.17) family.
