MRC Laboratory of Molecular Biology
One of the world's leading research institutes, our scientists are working to advance understanding of biological processes at the molecular level - providing the knowledge needed to solve key problems in human health.
The intracellular immune receptor TRIM21 detects antibody-bound viruses inside our cells and targets them for destruction by creation of a polyubiquitin signal. David Neuhaus’ group, with Leo James’, has shown that TRIM21 is both the enzyme and recipient of the ubiquitination.
The airways in our lungs are kept clear of mucus by the rhythmic beating motion of slender cellular extensions called cilia, driven by dynein motors. Andrew Carter’s group, has discovered a novel protein that packages these molecular motors for delivery into the cilia.
Chris Russo’s, David Barford’s, Jan Löwe’s, and John Sutherland’s groups have together solved the structure of the inhibitor favipiravir-RTP in complex with the SARS-CoV-2 RNA-dependent RNA polymerase, providing new insight into its mechanism of action.
Scientists had thought that the protease furin was responsible for cleavage of the SARS-CoV-2 Spike protein to reveal the fusion machinery that enables infection, but new work from Leo James’ group shows that furin is not essential for SARS-CoV-2 infection.
Type 2 ILCs (ILC2s) play an important role in dealing with parasites and are implicated in allergy. Andrew McKenzie’s group has discovered that the transcription factor RORα acts as a checkpoint controlling divergence between T cell and ILC2 development.
Emmanuel Derivery’s group, in collaboration with David Baker’s group in Seattle, have, for the first time, re-engineered two proteins so that they assemble into a 2D material and used this design to investigate a fundamental process of cell biology, receptor endocytosis.
