DESCRIPTION:Speaker: Henrik Weyer\nhosted by Martin Loose\nAbstract: Intrac
 ellular processes must be precisely organized in space and time. A paradig
 matic example is the symmetric division of bacteria\, which\, in E. coli\,
  is orchestrated by the ATP-driven oscillation of Min proteins between the
  cell poles. Remarkably\, two proteins of the Min system are sufficient fo
 r this pattern-formation process. Even so\, this seemingly simple system f
 orms a kaleidoscope of different reactiondiffusion patterns in vitro\, wit
 hout clear connections to the in vivo patterns. We lack a comprehensive un
 derstanding of the patterns in vivo and in vitro. Here\, we show theoretic
 ally that changes in the membrane-binding of one of the proteins\, MinE\, 
 explain the differences between patterns in vivo and in vitro. We verify t
 his prediction in vitro by constructing pattern phase diagrams using wild-
 type proteins and by removing MinEs membrane targeting sequence. This show
 s that a conceptual reactiondiffusion system grounded in the known biochem
 istry of the Min proteins captures their diverse spatiotemporal self-organ
 ization quantitatively\, offering an instructive platform to study the phy
 siological implications of and the physical principles underlying the rich
  phenomenology of intracellular protein patterns.
