PHYSICAL PROPERTIES

motifs/domains
  • a dileucine motif in its N-terminal cytoplasmic domain (AP3B1 associates with acidic dileucine-based motifs to shuttle target proteins from the trans-Golgi to lysosomes)
  • HOMOLOGY
    Homologene
    FAMILY
  • proton-dependent oligopeptide transporters (PRT2/POT) family
  • CATEGORY transport carrier

    basic FUNCTION
  • involved in proton-dependent uptake of di- or tri-peptides, and to a minor extent tetra-peptides
  • may participate in the intestinal absorption of peptide-based agents
  • could participate to recycling of peptides derived from extracellular and lysosomal thyroglobulin proteolysis, both essential steps for thyroid hormone synthesis
  • with AP3B1, and Hermansky-Pudlak syndrome proteins, are required for Toll-like receptor signaling in plasmacytoid dendritic cells
  • obscure solute channel protein, essential for TLR-mediated signaling in plasmacytoid dendritic cells
  • may also have a role in maintaining the appropriate pH of the endosomal compartment as endosomal acidification is required for optimal TLR7 and TLR9 activation
  • required for Plasmacytoid dendritic cells (pDCs) sensing of TLR ligands, is required to control persistent viral infection
  • lysosome-resident, proton-coupled amino-acid transporter that moves histidine and oligopeptides from inside the lysosome to the cytosol of eukaryotic cells
  • SLC15A4 transporter activity was necessary for the TLR-triggered cytokine production
