New method reveals how proteins stabilize the cell surface

0

(Umea University) To withstand external mechanical stress and handle trafficking of various substances, a cell needs to adjust its surrounding membrane. This is done through small indentations on the cell surface called caveolae. In order to stabilize its membrane, cells use the protein EHD2, which can be turned on and off to alternate between an inactive closed form and an active open form. The discovery, made by Umeå University researchers and colleagues, was recently published in the journal PNAS.
