The main focus of my lab is on structure/function
studies of membrane proteins, especially those
involved in ion translocation and transport. Of
particular interest are voltage-gated sodium
channels: we have determined the
first
crystal structure of a sodium channel in its open
conformation . We have also determined the
first
crystal structures of complexes of a sodium
channel with several eukaryotic sodium channel
drugs, which we have shown block prokaryotic
channels, making this channel an excellent candidate
for drug discovery/development, and we
identified
for the first time the locations of the sodium
ions in the channel, and determined
the
structure of a full-length open activated sodium
channel which has revealed a
novel interaction motif and has identified
residues conserved across human and prokaryotic
channels, that are associated with disease states.
To do these studies, my lab uses the techniques of
X-ray crystallography, cryoEM, circular dichroism
spectroscopy, biophysical characterisation methods,
cloning and expression, bioinformatics, and
molecular modelling. We also correlate
structure/function studies by molecular dynamics
calculations and use a range of functional studies
(many in collaborative studies with
electrophysiology experts (including the Clapham,
DeCaen, and Hemmings labs) to examine
structure/function relationships for ion channels.
We have determined the conformational changes
associated with channel opening and closing, and the
locations of a number of widely used drugs within
the channel hydrophobic core and in the
intramembranous fenstrations, whilst showing the
effects of mutations on drug binding. These studies
extend our early crystalllography and NMR
structure/function studies on polypeptide ion
channels, including peptaibols, gramicidin and
alamethicin, which led to the first detailed
molecular views of ion channels.
Our work is/has been
supported by grants from the BBSRC, the Rosetrees Trust, the EPSRC,
the MRC, NIAA, NIH, IUPAC, Pfizer Neusentis, Bayer
Animal Health, CNPQ (Brazil), the Heptagon Fund,
EU Marie Curie Funding, and the Wellcome Trust.
