Starting signal for cell division

Researchers led by Peter Lenart and Monica Gobran have discovered a previously unknown function of the protein kinase Plk1: It regulates the timely onset of cell division. When the protein is inhibited, cells start dividing many hours later. The new findings may help to improve approaches for cancer therapies. more

Mitoribosomes are essential for the function of mitochondria, the power houses of our cells. Researchers in Göttingen have discovered how the human cell assembles mitoribosomes in a modular fashion. more

Egg cell maintenance

Female mammals, including humans, are born with all of their egg cells. Some egg cells therefore survive for several decades – and need to remain functional over this long time. Extremely long-lived proteins in the ovary seem to play an important role in this. They appear to help maintain fertility for as long as possible. more

A missing ‘motor’ causes our eggs to fail

Human eggs are missing an important protein, which acts as a molecular motor, as researchers have found out. Their findings open up new avenues for therapeutic approaches that could reduce chromosome segregation errors in human eggs. more

Building with DNA

Life on Earth developed from inanimate components. Can we recreate this process in the laboratory, and what tools do we need for this? Using DNA origami, the art of folding at a scale of just a few millionths of a millimetre, we are able to reconstruct individual cellular components. They may be capable of taking over important tasks in our bodies in future. more

Nothing works without the correct form: For most proteins, there are millions of ways in which these molecules, composed of long chains of amino acids, can be folded - but only one way is the right one. Researchers in the department "Cellular Biochemistry" at the Max Planck Institute for Biochemistry in Martinsried examine how this origami in cells works and what happens if something goes awry. Franz Ulrich Hartl and his team are interested in both the underlying mechanisms and the structure of the molecules involved.Further information more

About 12,000 proteins are produced in typical human cells – more than 120,000 various proteins in total. Matthias Mann at the Max Planck Institute of Biochemistry in Martinsried, Germany, has set himself the target of establishing a protein library of the human body. Not an easy project - because in contrast to genes, proteins are extremely variable. In addition, many various factors influence which proteins a cell produces. Nevertheless, Mann is able to identify the proteins with mass spectrometry, nanochromatography and special computer software. more
