Our skin and mucous membranes are protected by epithelial cells, which form a barrier that defends the body from the outside environment. This barrier function relies on specialized structures called ...

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 ...

A protein, called beta-actin, is implicated in this process of chromatin remodeling. Now, a new study shows that beta-ac-tin does play an essential role in regulating which gene programs are ...
