Gatekeepers of the genome

Transcription factors control gene activation in cells. By binding to specific segments of DNA, they enable the blueprints that code for cellular proteins to be produced. But how are such factors themselves regulated?

Motor proteins and membrane dynamics

Membranes composed of a lipid bilayer define the outer surface of nucleated cells (the plasma membrane) and delimit the vital organelles within these cells, such as mitochondria and nuclei. The membrane curvature determines ...

New deactivation mechanism for switch proteins detected

A new mechanism for the deactivation of switch proteins has been identified by researchers from Ruhr-Universität Bochum, headed by Professor Klaus Gerwert and Dr. Till Rudack from the Department of Biophysics, and the University ...

Study gives insight into sun-induced DNA damage and cell repair

A team led by a Baylor University researcher has published a breakthrough article that provides a better understanding of the dynamic process by which sunlight-induced DNA damage is recognized by the molecular repair machinery ...

Study of Arctic fishes reveals the birth of a gene—from 'junk'

Though separated by a world of ocean, and unrelated to each other, two fish groups—one in the Arctic, the other in the Antarctic—share a surprising survival strategy: They both have evolved the ability to produce the ...

Increased speed of engineered human cell response

Researchers from the National Institute of Chemistry in Slovenia have developed a novel approach to regulate human cell response, endowing cells to respond to extracellular stimuli in minutes instead of hours. The authors ...
