The conformational mechanism of a transporter protein is found to have profound and energetically costly effects on the morphology of the surrounding membrane.
A post-lysosomal cholesterol transport inhibitor reveals how the endoplasmic reticulum membrane regulates total cellular cholesterol by constantly monitoring a critical pool of cholesterol in the plasma membrane.
Auxiliary proteins play functional roles in modulating the assembly and activity of a non-canonical ABC transporter that is important for the maintenance of outer membrane lipid asymmetry.
Two thermodynamically distinct transport mechanisms operating within the same binding site explains the remarkable promiscuity of POT family transporters towards peptide and drug ligands.
The crystal structure of a ternary complex of a TonB-dependent transporter containing a signalling domain, bound to siderophore as well as TonB, provides mechanistic insights into siderophore uptake and signalling.
GRAMD1 proteins sense a transient expansion of the accessible pool of plasma membrane cholesterol and facilitate its transport to the endoplasmic reticulum at ER-PM contact sites.
A structure of the complete, membrane bound, COPII coat solved by sub-tomogram averaging reveals the arrangement of all protein subunits on the membrane and suggests a mechanism for coating heterogeneously-shaped carriers.
