Pattern formation in membranes due to electrostatic protein-lipid interacion — •Sergio Alonso1, Karin John2, and Markus Baer1 — 1Physikalisch-Technische Bundesanstalt, Berlin, Germany — 2Université J. Fourier, Grenoble, France
We study the formation of protein patterns near membranes of living cells by mathematical modelling. The formation of protein domains by electrostatic lipid-protein interactions and the nonequilibrium biochemical reaction cycle of proteins near the membrane give rise to complex dynamics. On the other hand, Calcium is a intracellular signal which controls numerous processes, including the activity of the proteins attached to the membrane. We incorporate the effects of the calcium in a previous model for the dynamics of such proteins in the membrane.
