Novo Nordisk Foundation awards DKK 255 million for establishing the world’s most powerful protein “microscope”

The Novo Nordisk Foundation is supporting the establishment of an ultra-modern research platform in Lund, Sweden. The platform will enable researchers to investigate proteins at a level of detail not previously possible and can thus form the basis for developing new drugs. Researchers from Aarhus University have had a strong impact on the…

Nordic network in Nobel Prize–winning technology

A new Danish-Swedish research alliance wants to advance understanding of how biological molecules look and behave. With support from the Novo Nordisk Foundation and the Knut and Alice Wallenberg Foundation, scientists at four universities in Denmark and Sweden will join forces to create a Nordic network in cryo-electron microscopy, whose…

Nanovault controls enzymes

Researchers from Aarhus University have now succeeded in building a nanovault of DNA strings that can control enzymes. The nanovault functions as a safe in which an enzyme can be stored away and where only a specific set of keys can shut down the enzyme again. Aarhus University has also become the headquarters of a European PhD school that will…

Danish researchers reveal how the MRSA bacterium handles stress

An international team of researchers has revealed a fundamental mechanism responsible for handling stress in staphylococci when they are exposed to antibiotics. It is expected that the research results eventually can be used to develop new antibiotics that circumvent such stress mechanisms.

Dual Roles of ZC3H18 in Nuclear RNA Metabolism. Schematic representation of the dual engagement of ZC3H18 in RNA transcription and decay processes.  Left: ZC3H18 interacts with the CBCA complex (CBC and the ARS2 protein) to regulate protein-coding gene transcription directly or indirectly. The question mark indicates the elusive role of the histone-interacting domain and its modification in facilitating ZC3H18 function.  Right: Short non-coding RNAs, exemplified here by 3’extended snRNAs, are targeted by ZC3H18 in a process requiring interaction with both the CBCA and NEXT complexes. Such RNA decay can also occur ZC3H18-independently via direct NEXT exosome targeting. C, CBCA-interacting domain; H, histone-interacting domain; N, NEXT-interacting domain.

Researchers reveal dual role for human RNA decay factor

Researchers at Aarhus University have characterized the human RNA decay factor ZC3H18 and discovered its unanticipated role in the production of protein-coding RNA. The new study, published this week in Cell Reports, therefore reveals a double-faced activity of ZC3H18 in nuclear RNA fate decisions.

The ion channel is composed by four domains which are colored in each their solid color. Middle: Ribbon diagram of human TRPM4. A calcium binding site belonging to one of the monomers is marked with a box. Right: A zoom-in on the calcium binding site with the coordinating residues represented by sticks and their helices in ribbons. The ribbon diagram is overlaid with the densities of the calcium structure (gray mesh) and the difference density (blue mesh) between the calcium-bound structure and the calcium-free structure.

A Channel in the Heart of the Matter

How cells control the movement of ions, electrically charged species, in and out of the cell is a grand puzzle, whose completion will allow a thorough fundamental understanding of human physiology. A Danish-American team of researchers has found a piece of the puzzle with their determination of two structures of the human calcium-activated cation…

Zebrafish used to identify disease mechanism for heart disease

In a large collaborative study between the Department of Clinical Medicine, the Department of Biomedicine, and the Department of Molecular Biology and Genetics, among others, the researchers have succeeded in identifying and characterising the consequences of a newly discovered mutation associated with cardiac arrhythmia.

Förster resonance energy transfer (FRET) combines laser light and ultra-sensitive cameras that send signals into an individual molecule. This signal spreads to the other colour molecule on the pump, which begins to transmit light of another colour. The group focuses on the relationship between the different colours, which is registered in a specially built light microscope. These measurements provide information about the pump’s movements. (Photo: Mateusz Dyla)
Illustrated here is the timeline for the pump function, which is now revealed in high time resolution. The curve shows the relationship between the measured fluorescent colours emitted from dyes bound to the pump. At left, the pump is open towards the interior of the cell and has bound calcium ions and absorbed the ATP molecule – in other words, it is ‘charged’. The next step is the new, key result: in the red field, the pump is in the previously unknown closed state, where it has enclosed the ions to be sent out of the cell. The final stage illustrated shows that the pump has opened and released calcium ions into the surroundings. From here, it cannot return to the highlighted state. (Illustration: Daniel Terry/Dyla)

The end of ‘Pump Fiction’

Our cells are capable of moving energy and material around to the places where they are required, and ensuring that the body works properly. But how do the cells do this in real time from the perspective of the individual molecule?

Llama-derived nanobodies as a new tool in solving crystal structure

Aarhus University scientists have developed miniature antibodies (nanobodies) that can be labelled on certain amino acids. This provides a direct route for solving new X-ray crystal structures of protein complexes important for gaining mechanistic understanding of cellular processes, which is important in the development of drugs.
