Equilibrium and non equilibrium processes that remodel membrane curvature. (a) Shown on the left are illustrations of (i) the scaffolding mechanism: a dimer of the classical BAR domain interacts with negatively charged lipids on the membrane, through its positively charged membrane facing residues and (ii) the spontaneous curvature induced by the asymmetric insertion of a protein. (b) Curvature fluctuations in a planar membrane due to (i) fission and fusion of transport vesicles, (ii) binding and unbinding kinetics of membrane associated proteins and (iii) change in the conformation of ion channels.
