A collaborative team from LMB’s Cell Biology and Structural Studies Divisions has visualized the mammalian protein synthesis and export machinery at near-atomic resolution. The new research helps explain how secreted proteins, such as hormones, can cross an otherwise impermeable membrane to exit the cell.
It has long been appreciated that cells communicate with each other via proteins that are either secreted or embedded in the cell’s surface.

Insights into how the Fanconi Anaemia core complex activates DNA repair
Research carried out by Eeson Rajendra from Lori Passmore’s group in the LMB’s Structural Studies Division, in close collaboration with KJ Patel from the LMB’s PNAC Division, has brought together LMB expertise in protein biochemistry and genetics to study the disease Fanconi Anaemia (FA). For the first time, they have isolated the intact FA core complex, and demonstrated which subunits are essential for monoubiquitination of FANCD2, which initiates the repair of damaged DNA in cells.
Novel lipid kinase structure lays the foundation for a new class of drugs
A collaboration between Roger Williams’ group here in the LMB’s Protein and Nucleic Acid Chemistry Division and Kevan Shokat’s group at the University of California, San Francisco has provided insight into potential targets for the design of a new class of anti-viral drugs.
Enteroviruses cause diseases including polio; hand, foot and mouth disease and the common cold, and there are currently no anti-viral treatments available to combat them.
Graphene: stronger than steel and now suitable for biological electron microscopy
Lori Passmore and Chris Russo from the LMB’s Structural Studies Division have discovered how to modify the new material graphene using low-energy hydrogen plasmas, to allow it to bind proteins. This discovery makes it suitable for use in electron microscopy to solve protein structures.
Graphene, which was only discovered in 2004, is a two-dimensional carbon sheet that is one of the strongest and thinnest materials known.
New technique identifies protein production in specific cells at specific times
Research undertaken by Jason Chin’s group, in the LMB’s Centre for Chemical and Synthetic Biology (CCSB), part of the Protein and Nucleic Acid Chemistry Division, has successfully developed a novel and versatile technique to identify proteins produced in a particular set of cells at a particular time.
Individual sets of cells in the body of an animal are specialised to do different things.
