Turning cells into computers with protein logic gates

The same basic tools that allow computers to function are now being used to control life at the molecular level. The advances have implications for future medicines and synthetic biology.

Researchers map structure of key chromatin-remodeling complex

Northwestern University researchers have mapped a group of proteins that play a critical role in both gene expression and repairing damaged DNA. By understanding this protein complex, called SWI/SNF, researchers hope to better ...

Unraveling gene expression

The DNA of a single cell is two to three meters long end-to-end. To fit in the nucleus and function correctly, DNA is packaged around specialized proteins. These DNA-protein complexes are called nucleosomes, and they are ...

Capturing extreme close-ups of cellular gene expression

Scientists studying genetic transcription are gaining new insights into a process that is fundamental to all life. Transcription is the first step in gene expression, the process taking place within all living cells by which ...

Blue light for RNA control

Messenger RNA molecules contain genetic information and thus control the synthesis of proteins in living cells. Biochemists at the University of Bayreuth and the University of Bonn have now discovered a way to regulate this ...

Protein expression

Protein expression is a subcomponent of gene expression. It consists of the stages after DNA has been translated into polypeptide chains, which are ultimately folded into proteins. Protein expression is commonly used by proteomics researchers to denote the measurement of the presence and abundance of one or more proteins in a particular cell or tissue.
