Actin achieves this by assembling into filaments, one actin molecule at a time. The proteins of the formin family are pivotal partners in this process: positioned at the filament end, formins ...

New research sheds light on one of the biggest questions in biology: where did complex life come from? The answer may lie ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

Scientists reveal the role of hidden microbes called Asgard archaea in the origins of complex life, challenging long-held ...

Actin achieves this by assembling into filaments, one actin molecule at a time. The proteins of the formin family are pivotal ...

Gamma-actin therefore confers increased rigidity to the apical membrane, forming a network of filaments that is stronger and stiffer than that made up of beta-actin filaments. "This result is ...

An individual sarcomere contains many parallel actin (thin) and myosin (thick) filaments. The interaction of myosin and actin proteins is at the core of our current understanding of sarcomere ...

ETH researchers discovered related structures in Asgard archaea and describe their structure. These experiments show that ...

Our skin and mucous membranes are protected by epithelial cells. This 'barrier' tissue performs its function thanks to specialized structures called 'junctions'. They ensure cell cohesion and regulate ...
