A polar SxxS motif drives assembly of the transmembrane domains of Toll-like receptor 4

Like all members of the Toll-like receptor (TLR) family, TLR4 comprises of a large ectodomain (ECD) involved in ligand recognition at the cell-surface, and a cytosolic Toll/interleukin-1 receptor (TIR) signalling domain, linked by a lipid membrane-anchored transmembrane (TM) domain (TMD).

Full-length, Oligomeric Structure of Wzz Determined by Cryoelectron Microscopy Reveals Insights into Membrane-Bound States

Wzz is an integral inner membrane protein involved in regulating the length of lipopolysaccharide O-antigen glycans and essential for the virulence of many Gram-negative pathogens. In all Wzz homologs, the large periplasmic domain is proposed to be anchored by two transmembrane helices, but no information is available for the transmembrane and cytosolic domains. Here we have studied purified oligomeric Wzz complexes using cryoelectron microscopy and resolved the transmembrane regions within a semi-continuous detergent micelle.
