Researchers from Tohoku University developed a unique chemical reaction to attach two distinct functional molecules to the N-terminus of peptides with a glycine amino acid, achieving site-selective modification and stable carbon-carbon bonds. The method shows potential for labeling diverse peptides and larger proteins for purification,...
Researchers at UTSA have discovered a novel strategy to inhibit the spread and infection of Vibrio cholerae, the bacteria responsible for cholera. They identified a peptide-binding domain that can disrupt the virulence of V. cholerae, preventing intestinal colonization and biofilm formation.
Researchers from Universitat de Barcelona and Universitat Internacional de Catalunya discuss the non-receptor protein tyrosine kinase Src as a good example of an oncogene. Targeting the Src N-terminal regulatory element (SNRE) has potential as oncotargets to inhibit Src activity only in cancer cells.
A new study published in the Journal of the American Heart Association found that elevated levels of two protein biomarkers associated with heart damage were linked to undetected or symptomless cardiovascular disease in adults with Type 2 diabetes. The study analyzed health information and blood samples from over 10,300 adults and foun...
A germline mutation of topoisomerase II B affects the movement of proteins in the nuclei of cells with this mutation. The study reveals that the mutation impacts nuclear dynamics and provides a platform to understand the biological relevance of such mutations.
A new study by the University of Colorado Anschutz Medical Campus explores the effects of multiple mutations in SARS-CoV-2 variants. The findings suggest that certain mutations work together to improve virus fitness, making it challenging for antibody treatments to neutralize new variants.
The Epsilon variant's unique mutations in the spike protein reduce antibody neutralization, making it harder for vaccines and past infections to fight. The study reveals an unprecedented mechanism behind this loss of immunity, shedding light on a new strategy for immune evasion.
Scientists have discovered a lesser-known site on the pandemic coronavirus that is recognized by COVID-19 infection-fighting antibodies, which potently prevent the virus from infecting cells.
