Chromosome-folding theory shows promise
Human chromosomes are much bigger and more complex than proteins, but like proteins, they appear to fold and unfold in an orderly process as they carry out their functions in cells.
Discovery of an unexpected function of a protein linked to neurodegenerative diseases
Until today, the proteins known as ubiquitin receptors have been associated mainly with protein degradation, a basic cell cleaning process. A new function now described for the protein dDsk2 by the team headed ...
How an RNA gene silences a whole chromosome
Researchers at Caltech have discovered how an abundant class of RNA genes, called long non-coding RNAs (lncRNAs, pronounced link RNAs) can regulate key genes. By studying an important lncRNA, called Xist, ...
New 3-D method improves the study of proteins
Researchers have developed a new computational method called AGGRESCAN3D which will allow studying the 3D structure of folded globular proteins and substantially improve the prediction of any propensity for ...
Scientists gain unique insight into the function of a key muscle protein
Thanks to the first high-resolution structural analysis of the muscle protein α-actinin, scientists now have a better understanding of how muscles work. The analysis provides crucial information about the ...
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 ...
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.
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.
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.
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 ...
Chinese team performs gene editing on human embryo
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, ...
Poor diet may contribute to the decline in British bees
The changing British landscape could be contributing to the decline in our bee populations, according to Lancaster University research.
