Summary
PMID 18305481
UNC93B1 is a polytopic membrane protein that delivers the nucleotide sensing receptors TLR7 and TLR9 from the endoplasmic reticulum to endolysosomes.
PMID 19451267
UNC93B1 biases Toll-like receptor responses to nucleic acid in dendritic cells toward DNA- but against RNA-sensing.
PMID 20865117
UNC93B1 associates with Toll-Like Receptor (TLR) 3, TLR7 and TLR9, mediating their translocation from the endoplasmic reticulum to the endolysosome, hence allowing proper activation by nucleic acid ligands. UNC93B1 has a critical role on induction of IL-12/IFN-gamma production as well as autonomous control of Toxoplasma replication by macrophages.
PMID 21683627
UNC93B1 controls homeostatic TLR7 activation by balancing TLR9 to TLR7 trafficking from endoplasmic reticulum to endolysosomes. D34A mutation in UNC93B1 causes TLR7-dependent systemic lethal inflammation. (Demonstrated in murine model)
PMID 21683627
UNC93B1 is a multitransmembrane endoplasmic reticulum (ER)-resident protein that controls homeostatic TLR7 activation by balancing TLR9 to TLR7 trafficking. Mice harboring a D34A mutation in Unc93b1 show Tlr7-dependent, systemic lethal inflammation.
PMID 22164301
UNC93B1 participates in intracellular trafficking and signalling for all nucleotide-sensing Toll-like receptors (TLRs).

Summary
PMID 21097503
[Mus musculus] Unc93b1 is a resident endoplasmic reticulum protein that interacts with Tlr11 to regulate the dendritic cell activation in response to T. gondii profilin and parasitic infection.

Entrez Gene
Summary This gene encodes a protein with similarity to the C. elegans unc93 protein. The Unc93 protein is involved in the regulation or coordination of muscle contraction in the worm. [provided by RefSeq, Jul 2008]
