filaments. The interaction of myosin and actin proteins is at the core of our current understanding of sarcomere shortening. How does this shortening happen? It has something to do with a sliding ...

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 ...

Our skin and mucous membranes are protected by epithelial cells, which form a barrier that defends the body from the outside ...

This function relies to a large extent on the presence of "adherens" and "tight junctions," veritable protein ... of filaments that is stronger and stiffer than that made up of beta-actin filaments.

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

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

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

has a similar function to actin – the most abundant protein in the majority of human cells. In the presence of a chemical called ATP, actin molecules can join together into long spiral chains known as ...

Researchers have studied the role of a specific protein, gamma-actin ... that is stronger and stiffer than that made up of beta-actin filaments. "This result is particularly interesting because ...
