Toll-like receptor (TLR) 3 is an endosomal TLR that mediates immune responses against viral infections upon activation by its ligand double-stranded RNA, a replication intermediate of most viruses. TLR3 is expressed widely in the body and activates both the innate and adaptive immune systems [1]. This entry represents the Toll-like receptor 3 trans-membrane domain which has been shown to form dimers and trimers with different surfaces for helix-helix interaction [2].	Domain
