Proposed conformational equilibrium of S1R. ( A ) Schematic depiction of dynamic monomer (DM) conformation and anchored monomer (AM) conformations of S1R. Possible movements of H1 α-helix (m1), H4/5 α-helices (m2) and unfolding of BIND domain (m3) are shown. The equilibrium between DM and AM conformations is affected by S1R agonists, S1R antagonists, cholesterol (CHO) in the membrane and E102Q pathogenic mutation, as shown. ( B ) Proposed distribution of different S1R conformations. AM conformation is well defined and forms a narrow peak in conformational space. DM conformation is a spectrum of molecular species that differ from each other in the tilt of H1 α-helix, position of H4/5 α-helices relative to the surface of the membrane and the folding state of BIND domain. As a result, DM conformation forms a broad peak in conformational space.

Proposed mechanism of S1R oligomerization. ( A ) S1R in the AM monomeric form promotes the generation of large oligomers due to the formation of BIND-BIND trimers and H1-H1 dimers. Large oligomers are stabilized in the presence of cholesterol (CHO) or S1R antagonists. ( B ) S1R agonists cause the conversion of AM conformation of S1R to DM conformation resulting in a loss of BIND-BIND and H1-H1 intramolecular associations and the disassembly of large S1R oligomers and clusters.
