The team captured molecular ‘snapshots’ of RNF216 as it assembled chains of the small protein ubiquitin, which tags the target proteins to modify their behaviour in the cell.

But for baby proteins newly biosynthesized on ribosomes, obtaining structural pictures has proved ... without assistance from large protein complexes called molecular chaperones.

The inset shows the molecular and chemical structure of the protein, miRFP718nano. [Junjie Yao, Duke University] Imaging deep tissues with light is challenging.

Biomedical and genetic engineers at Duke University and the Albert Einstein College of Medicine have designed a small fluorescent protein that emits and absorbs light that penetrates deep into ...

When proteins are made in a cell, they start out as strings of amino acids, which have to be folded into the correct, 3D ...

Single-protein imaging shows that the Pol IV DNA repair protein (red) moves along the DNA strand (green) with the complex that copies DNA (replisome). Credit: Tuan Pham, UC Davis “To use the analogy ...

Researchers found a rare example of an ancient protein that can still function in a molecular mirror world – offering new clues about the evolutionary history of proteins that bind to nucleic acids.

Retinol-binding protein 3 (RBP3) is a glycoprotein of about 140 kDa, found in the intercellular space of the retina. It plays an important role in the transport of retinoids—molecules essential ...
