Proteins for anxiety in humans and moulting in insects have common origin
Neuropeptides are small proteins in the brains of all animals that bind to receptor proteins and cause activity in cells. The researchers at Queen Mary University of London, led by Professor Maurice Elphick, ...
All will be illuminated: Real-time multicolor imaging with luminescent protein-based Nano-lanterns
Happily ever after: Scientists arrange protein-nanoparticle marriage
Fastening protein-based medical treatments to nanoparticles isn't easy. With arduous chemistry, scientists can do it. But like a doomed marriage, the fragile binding that holds them together often separates.
Chemists create modular system for placing proteins on membranes
With a tag, an anchor and a cage that can be unlocked with light, chemists have devised a simple, modular system that can locate proteins at the membrane of a cell.
Protein harnesses power of 'silly walks'
The 'stiff-legged' walk of a motor protein along a tightrope-like filament has been captured for the first time.
Viral proteins may regulate human embryonic development
A fertilized human egg may seem like the ultimate blank slate. But within days of fertilization, the growing mass of cells activates not only human genes but also viral DNA lingering in the human genome from ...
Scientists describe protein pumps that allow bacteria to resist drugs
Research teams led by Edward Yu of Iowa State University and the Ames Laboratory have described the structures of two proteins they believe pump antibiotics from bacteria, allowing the bacteria to resist ...
Messenger RNA-associated protein drives multiple paths in T-cell development, study finds
RNA is both the bridge between DNA and the production of proteins that carry out the functions of life and what guides which and how much protein gets made. As messenger RNA (mRNA) is transcribed from DNA ...
How to kill a protein
For decades scientists have been looking closely at how our cells make proteins. But the inverse is equally important: how cells kill them.
Electron transfer challenges common fluorescence technique
Tryptophan is an amino acid, one of the building blocks of proteins. It is used extensively to study how proteins change their 3D structure, and also how they interact with other proteins and molecules. This is studied with ...
Detailed structure of human ribosome revealed
A team at the Institut de Génétique et de Biologie Moléculaire et Cellulaire (IGBMC - CNRS/Université de Strasbourg/Inserm) has evidenced, at the atomic scale, the three-dimensional structure of the complete ...
Improving accuracy in genome editing
Imagine a day when scientists are able to alter the DNA of organisms in the lab in the search for answers to a host of questions. Or imagine a day when doctors treat genetic disorders by administering drugs ...
Cell's protein-making machines shift modes under stress
Similar to a hybrid car that switches from gas to electric as it drives on major highways and secondary roads, Cornell researchers have discovered that the cell's protein-making machinery, called ribosomes, ...
Researchers find possible universal code of protein structure
A Dartmouth College study finds there may be a universal code to predict protein structure, which could help to determine why certain mutations cause disease and how to fix them.
