Berkeley Lab Berkeley Lab Researchers Take an Atomic-Scale Look at Key Cellular Protein A pathway to the design of even more effective versions of the powerful anti-cancer drug Taxol has been opened with the most detailed look ever at the assembly and disassembly of microtubules, tiny fibers of tubulin protein that form the cytoskeletons of living cells and play a crucial role in mitosis. Through a combination of high-resolution cryo-electron microscopy (cryo-EM) and new methodology for...

SEATTLE, May 15, 2014 /PRNewswire-USNewswire/ -- Known for its advocacy of intelligent design, Discovery Institute has released The Workhorse of the Cell: Kinesin, a dramatic new three-minute video revealing what could be the most visually stunning molecular machines in cells, called kinesins. The animation provides a new presentation of evidence for intelligent design at the cellular level. "It's one thing to tell someone, 'Hey, kinesins are key transport proteins within the cell.'...

Scientists Develop Nanotrain Network

[ Watch The Video: Nanotrain Transport System ] University of Oxford Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists at Oxford University and Warwick University. The system can construct its own network of tracks spanning tens of micrometres in length, transport cargo across the network and even dismantle the tracks. The work is published in Nature Nanotechnology and was supported by the Engineering...

Published in the Proceedings of the National Academy of Sciences, the Study by Erkan Tuzel and Scientists at UMass Amherst Provides New Insights into a Cellular System Whose Failure Can Lead to Neurodegenerative Diseases and Cancer. Worcester, MA (PRWEB) December 14, 2012 The interior of an animal cell is like a small city, with factories–called organelles–dedicated to manufacturing, energy production, waste processing, and other life functions. A network of intercellular...

Researchers from the Department of Chemistry and Molecular Biology at the University of Gothenburg have managed for the first time to obtain detailed information about the role of the protein metastasin in the spread of tumor cells. Published recently in the renowned Proceedings of the National Academy of Sciences (PNAS), the study paves the way for the development of new drugs. Metastasin is a protein with a key role in the spread of tumor cells. Previous research has shown that it is...

A new study in the Journal of General Physiology (www.jgp.org) uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) "walk" along their actin track. The myosin superfamily of mechanoenzymes, more commonly referred to as molecular motors, play an important role in muscle contraction and other basic cellular processes. MyoV, one of the most highly studied molecular motors, has the ability to travel long distances by taking multiple...

Just like people, some proteins have characteristic ways of "walking," which (also like human gaits) are not so easy to describe. But now scientists have discovered the unique "drunken sailor" gait of dynein, a protein that is critical for the function of every cell in the body and whose malfunction has been associated with neurodegenerative disorders such as Lou Gehrig's disease and Parkinson's disease. The research, which was led by Samara Reck-Peterson of Harvard Medical School and...

[ Watch the Video ] A biological model system that dead-ends in an 'absorbing state' Supplied with sufficient energy, a freight train would ride the rails as far as they go. But nature also knows systems whose dynamics suddenly turn into a kind of endless loop. Like in a hamster wheel, a train caught up in such a system would continue running, but without moving forward. Scientists from the Cluster of Excellence Nanosystems Initiative Munich have now succeeded in building a simple model...

How a molecular traffic jam impacts cell division Interdisciplinary research between biology and physics aims to understand the cell and how it organizes internally. The mechanisms inside the cell are very complicated. LMU biophysicist Professor Erwin Frey, who is also a member of the Cluster of Excellence “Nanosystems Initiative Munich” (NIM) is working with his group on one particular issue involved in the cell´s life. The professor for statistical and biological physics...
