It all starts with protein purification.
Science and large rodents ...
We study the architecture of protein complexes using cryo-electron microscopy.
We use X-ray crystallography to study protein function in signal transduction.
TNKS2 SAM domain filaments: some signalling proteins polymerise to switch functional states.
We aim to reconstitute signalling complexes from purified proteins to recapitulate their activities in the cell.
Punctate subcellular localisation reflects polymerisation of this signalling protein.
We use structural and biochemical information to interrogate protein function in cells.
Happy pipetting!
We have used X-ray crystallography to reveal the mechanism of tankyrase polymerisation.
X-ray crystallography provides detailed insights into protein mechanisms.
Our lab is located at the Chelsea site of ICR in central London. This is the view from the top floor.
A GPU system for our cryo-EM work: of course the coolant had to be green.

Great news just before Christmas: we are delighted to have been awarded a 5-year Wellcome Trust Investigator Award to study molecular mechanisms of telomere maintenance. Watch this space for new postdoc positions in Structural Biology and Telomere Biology!
PhD student Yexin has been awarded a Boehringer Ingelheim Fonds Travel Grant to attend the 8th Brazil School for Single-Particle Cryo-EM. Many congratulations to Yexin, and many thanks to the Boehringer Ingelheim Fonds!
Today we welcome two new PhD students to our team: Iona Black and Sam Hibbs. Two highly collaborative projects with the Collins and Lord teams at ICR are waiting for them.
