Researchers have identified that Dishevelled doesn’t only function in the cytoplasm and at the cell membrane – it must also pass into the nucleus. A study published today in Journal of Biology reveals that Dishevelled, a key player in the Wnt/beta-catenin signalling pathway, has to be localised in the nucleus to perform a key aspect of its function. This discovery should shed light on both normal embryonic development and the development of cancer.
In the paper, Sergei Sokol and colleagues, from Harvard Medical School, show that Dishevelled (Dsh) is constantly shuttling between the nucleus and the cytoplasm, owing to its nuclear export and import sequences, but that it has to be in the nucleus to respond to certain Wnt signals transmitted through the ‘canonical’ Wnt signalling pathway.
Dsh has always been considered to be a cytoplasmic protein, exerting its function as a stabiliser of beta-catenin in the cell cytoplasm after stimulation by Wnt secreted ligands binding to Frizzled receptors on the cell surface.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
