    basic FUNCTION
  • delivering the nucleotide-sensing receptors TLR7 and TLR9 from the endoplasmic reticulum (ER) to the endolysosomes
  • can control the functional pool of TLR9 by regulating exit from the ER
  • with CNPY3, and HSP90B21, play a role in TLR localisation
  • critical role for UNC93B1 on induction of IL12/IFNG production as well as autonomous control of Toxoplasma replication by macrophages
  • upon activation, TLR7 and 9 are transported from the endoplasmic reticulum (ER) to endolysosomes for nucleic acid sensing by an ER-resident protein, UNC93B1
  • participates in intracellular trafficking and signaling for all nucleotide-sensing TLRs, but the mode of regulation of TLR localization differs for each TLR
  • involved in Toll-like receptor activation
  • UNC93B1 expression is required for TLR3 cleavage and signaling
  • multipass transmembrane protein required for TLR3, TLR7, TLR9, TLR11, TLR12, and TLR13 function, controls trafficking of TLRs from the endoplasmic reticulum (ER) to endolysosomes
  • essential for trafficking of endosomal TLRs from the endoplasmic reticulum to endosomes

    protein
  • controls homeostatic TLR7 activation by balancing TLR9 to TLR7 trafficking
  • essential for intracellular trafficking and endolysosomal targeting of TLR7 and TLR9
  • is required for processing by transporting TLR3 through the Golgi complex and to the endosomes
  • TLR3 is an important regulator of UNC93B1 that in turn governs the responsiveness of all nucleic acid-sensing (NAS) Toll-like receptors (TLRs)
  • to restrict Nucleic acid (NA)-sensing in endolysosomes, TLR7/9 trafficking is tightly controlled by a multiple transmembrane protein UNC93B1
  • upon ligand stimulation, LRRC59 associated with UNC93B1 in a TLR-independent manner, which required signals induced by ligand internalization
