The functions of biomolecules, including lipids, nucleic acids and especially proteins are determined to a great extent by their structure. This structure–function relationship is a foundation of many ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

Proteins carry out many of an organism's critical functions, and they are coded for by genes. To make a protein from a gene, a cell first needs a copy of the gene in the form of a molecule called RNA.

Researchers have found a new, dynamic protein structure in cells. Every cell contains millions of protein molecules. Some of them have the ability to phase-separate to form non-membrane-bound ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...
