About Us

The MRC Laboratory of Molecular Biology (LMB) is a research institute dedicated to the understanding of important biological processes at the levels of atoms, molecules, cells and organisms. In doing so, we provide knowledge needed to solve key problems in human health.

Our scientists tackle fundamental, often difficult and long-term research problems. The LMB has made revolutionary contributions to science, such as pioneering X-ray crystallography to determine protein structures, the sequencing of DNA and the development of monoclonal antibodies. Eleven Nobel Prizes have been awarded for work carried out by LMB scientists.

The LMB also promotes the application and exploitation of our research findings, both by collaboration with existing companies and the founding of new ones, helping to advance medical research and the translation and application of knowledge.

The LMB provides an unsurpassed environment for both young and established researchers, with state-of-the-art facilities and a unique scientific culture. The LMB has always been very diverse, with a truly international outlook. We currently employ men and women from over 50 countries, and LMB alumni work in research organisations across the world.

Insight on Research

Cryo-electron microscopy reveals near-atomic resolution structure of the prespliceosome

Two alternative splicing factors

Kiyoshi Nagai’s group in the LMB’s Structural Studies Division have used electron cryo-microscopy to solve the structure of the prespliceosome at near-atomic resolution, providing new insights into how the spliceosome is assembled and regulated. The human genome contains approximately 20,000 genes, which…

Discovering how translation and mRNA decay are linked

Gel showing global poly(A) tail lengths which shorten over time

Scientists in Lori Passmore’s group in the LMB’s Structural Studies Division have revealed new mechanistic insights into the link between translation and mRNA decay. In collaboration with Jeff Coller’s group at Case Western Reserve University, USA, and Brenton Graveley’s group at the…
