Biologists glean insight into repetitive protein sequences
About 70% of all human proteins include at least one sequence consisting of a single amino acid repeated many times, with a few other amino acids sprinkled in. These "low-complexity regions" are also found in most other organisms......»»

Ancient protein structure may have enabled early molecular evolution and diversification
In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is completely absent in modern proteins......»»
Filament structure found to activate and regulate CRISPR-Cas "protein scissors"
CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, al.....»»
Protein involved in the early stages of age-related macular degeneration offers hope for prevention
Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss in the United States. Despite existing treatments, the underlying causes of this disease and effective therapies remain elusive. Research published in the journal D.....»»
Researchers determine how a protein contributes to human immune defense against RNA viruses
An international research team led by Prof. Dr. Janosch Hennig from the University of Bayreuth has discovered how the TRIM25 protein contributes to defense against RNA viruses whose genetic material is contained as ribonucleic acid (RNA)......»»

Protein study reveals how the tiny shrew achieves a resting heart rate of 1,020 beats per minute
The shrew's resting heart rate can reach up to 17 beats per second, equivalent to about 1,020 beats per minute. In comparison, the average human resting heart rate is around 60 to 100 beats per minute, making the shrew's resting heart rate approximat.....»»
Saturday Citations: Octopuses as shift supervisors for fish; universe confounds standard model; extremely old cheese
This week, biologists tracked down a mysterious group of orcas near Chile; Hubble spotted a black hole jet that causes stars along its trajectory to erupt; and researchers explained mysterious craters that began appearing in Siberian permafrost in th.....»»
Trimer complex TaNF-Y balances grain yield and quality in wheat: Study
Breeding efforts have focused intensively on improving grain yield and quality in wheat (Triticum aestivum L.). Content and composition of grain starch and seed storage protein (SSP) are two critical factors that determine grain yield and quality. St.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Want an RTX 5090? Prepare to wait a little longer
The latest reports suggest that Nvidia's RTX 5090 won't be released this year. On the upside, a few more leaks give us more insight into the card's specs......»»
