Detangling DNA replication

DNA is a lengthy molecule—approximately 1,000-fold longer than the cell in which it resides—so it can't be jammed in haphazardly. Rather, it must be neatly organized so proteins involved in critical processes can access ...

The gene code of growing limbs

When a fetus develops, cell division and differentiation, gene expression, cell-to-cell signaling, and morphogenesis must be carefully coordinated to occur in the correct sequence and for the proper amount of time. Failures ...

Protein for deeper insights into the brain

To be able to examine the function of individual cells or structures in intact tissue, these need to be visible. This may sound trivial, but it is not. To achieve this, researchers implant fluorescent proteins into cells. ...

How infectious bacteria hibernate through treatment

Disease-causing bacteria can develop resistance to antibiotics which are then no longer effective in treating infection, yet they also have another tactic to avoid being killed off by antibiotic treatment. Some cells of the ...

Molecular switches are not just 'on' or 'off'

The GTPases constitute a very large protein family, whose members are involved in the control of cell growth, transport of molecules, synthesis of other proteins, etc. Despite the many functions of the GTPases, they follow ...

First interactive model of human cell division

Mitosis—how one cell divides and becomes two—is one of the fundamental processes of life. Researchers at EMBL have now produced the first interactive map of proteins that make our cells divide, allowing users to track ...

Hsp90—more than just a chaperone

Researchers from the Verstreken lab (VIB-KU Leuven) have identified a completely novel function for Hsp90, one of the most common and most studied proteins in our body. In addition to its well-known role as a protein chaperone, ...
