Researchers outline how they used a chemical probe to light up interlocking peptides. Their technique will help scientists differentiate synthetic peptides from toxic types found in Alzheimer's ...

As people around the world marveled in July at the most detailed pictures of the cosmos snapped by the James Webb Space Telescope, biologists got their first glimpses of a different set of images — ...

Researchers at the University of Toronto have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides – chains of amino acids that are shorter than proteins, ...

The human leukocyte antigens (HLA-I) are multi-subunit complexes that localize to the cell surface and present bound peptides to nearby immune cells. The study of these HLA peptide-presenting ...

Jia’s team developed a protocol to improve the screening of protein pockets. This involved identifying the pockets, removing ...

One of the hallmarks of Alzheimer's disease is the clumping of proteins called Tau, which form tangled fibrils in the brain.
