Researchers have discovered how unstructured segments of surface proteins regulate the biological function of a cell. Their ...

The amount of any given protein in a cell has to be controlled to keep its levels within a range required for healthy ...

Proteomics is the large-scale study of proteins, particularly their structures and functions. It involves the systematic identification, quantification, and analysis of the entire protein complement ...

A new artificial intelligence (AI) tool that draws logical inferences about the function of unknown proteins promises to help scientists unravel the inner workings of the cell. Developed by KAUST ...

Convergent evolution—where distinct species independently evolve similar traits or functions, such as the wings of birds and ...

Recent advancements in mass spectrometry and computational tools enhance the feasibility of top-down proteomics. Top-down ...

Bacteria insert proteins into their outer membrane using a highly conserved apparatus known as the β-barrel assembly ...

Protein glycosylation is a post-translational/co-translational covalent attachment of glycans to the amino acid side chains of proteins. Severe acute respiratory ...

This story is part of a larger series on viroids and virusoids, small infectious RNAs. It is also the third installment in a series on hepatitis D virus, a virusoid-like pathogen that causes serious ...

Viruses are invading pathogens that infect host cells and rapidly replicate throughout the body. They carry a small piece of genetic material such as DNA or RNA surrounded by a capsid that needs a ...

Protein is vital for body functions, and its deficiency manifests in six key ways: brittle hair, muscle weakness, swelling, ...
