(Phys.org) —Proteins accomplish something rather amazing: A protein can have many functions, with a given function being determined by the way they fold into a specific three-dimensional geometry, or conformations. Moreover, ...
In a new Nature Communications study, researchers have explored the construction of genetic circuits on single DNA molecules, demonstrating localized protein synthesis as a guiding principle for dissipative nanodevices, offering ...
Researchers from Southwest University in China have constructed the entire chromosomal-scale genome assembly and complete spidroin gene set of the golden orb-weaving spider, Trichonephila clavata, known for its especially ...
In human chromosomes, DNA is coated by proteins to form an exceedingly long beaded string. This "string" is folded into numerous loops, which are believed to help cells control gene expression and facilitate DNA repair, among ...

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.
