Active and inactive orientations of the transmembrane and cytosolic domains of the erythropoietin receptor dimer.
Binding of erythropoietin to the erythropoietin receptor (EpoR) extracellular domain orients the transmembrane (TM) and cytosolic regions of the receptor dimer into an unknown activated conformation.Expand

A conformational switch in complexin is required for synaptotagmin to trigger synaptic fusion
The crystal structure of complexin bound to a prefusion SNAREpin mimetic shows that the accessory helix extends away from the SNAREpin in an 'open' conformation, binding another SNAREpin andExpand

Membrane topography of the hydrophobic anchor sequence of poliovirus 3A and 3AB proteins and the functional effect of 3A/3AB membrane association upon RNA replication.
Replication of poliovirus RNA takes place on the cytoplasmic surface of membranous vesicles that form after infection of the host cell. It is generally accepted that RNA polymerase 3D(pol) interactsExpand

Calcium sensitive ring-like oligomers formed by synaptotagmin
Significance Synaptotagmin-1 is the calcium sensor for synchronous neurotransmitter release. It couples calcium influx to the soluble N-ethylmaleimide–sensitive factor activating protein receptorExpand

Re-visiting the trans insertion model for complexin clamping
We have previously proposed that complexin cross-links multiple pre-fusion SNARE complexes via a trans interaction to function as a clamp on SNARE-mediated neurotransmitter release. A recent NMRExpand

Spatial relationship between the prodan site, Trp-214, and Cys-34 residues in human serum albumin and loss of structure through incremental unfolding.
Prodan (6-propionyl-2-(dimethylamino)-naphthalene), a competitive inhibitor of warfarin binding to human serum albumin (HSA) at drug site I, was used to determine the inter- and intradomain distancesExpand

The control of transmembrane helix transverse position in membranes by hydrophilic residues.
The ability of hydrophilic residues to shift the transverse position of transmembrane (TM) helices within bilayers was studied in model membrane vesicles. Transverse shifts were detected byExpand

Nanodisc-cell fusion: control of fusion pore nucleation and lifetimes by SNARE protein transmembrane domains
The initial, nanometer-sized connection between the plasma membrane and a hormone- or neurotransmitter-filled vesicle –the fusion pore– can flicker open and closed repeatedly before dilating orExpand

Glutamate-induced Assembly of Bacterial Cell Division Protein FtsZ*
The polymerization of FtsZ is a finely regulated process that plays an essential role in the bacterial cell division process. However, only a few modulators of FtsZ polymerization are known. WeExpand
