Abstract excerpt
TLRs are divided into two groups based on their subcellular localization patterns. TLR1, 2, 4, 5, and 6 are expressed on the cell surface, whereas the nucleotide-sensing TLRs, such as TLR3, 7, 8, and 9 stay mainly inside cells. The polytopic membrane protein UNC93B1 physically interacts with the nucleotide-sensing TLRs and delivers them from the endoplasmic reticulum to endolysosomes, where the TLRs recognize...
