Cavin1 intrinsically disordered domains are essential for fuzzy electrostatic interactions and caveola formation

Abstract

Caveolae are spherical nanodomains of the plasma membrane generated by assembly of caveolin and cavin proteins. Here, the authors show that fuzzy electrostatic interactions between caveolin-1 and Cavin1 proteins, combined with membrane lipid interactions, are required to generate membrane curvature and a metastable caveola coat.
