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 partners in this process: positioned at the filament end, formins ...

A recently identified bacterial protein structure is contributing to the design of novel anticancer drug delivery systems.

The actin filament exists as a structure of the fixed length and bears the muscle contraction and the adjustment on a muscular inside. The circulation and the molecule movements of the polymerization ...

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 ...

The authors point out that, in low concentrations of ATP, when the myosin heads both remain bound to the actin filament, the molecule often seems to be straining forward, in the form of a ...

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 ...

Thin, flexible protein strands called actin filaments act like bones for our cells and are critical for its movement. Supercomputer simulations have helped solve a decades-old mystery of how actin ...

The organization and dynamics of actin filaments must be precisely controlled during these processes, and consequently defects in regulation of the actin cytoskeleton lead to various diseases ...
