DESCRIPTION:Speaker: Jack Taunton\nAbstract: Actin polymerization drives me
 mbrane movement and is spatially\nregulated by membrane-associated signali
 ng complexes. Rho-family\nGTPases (such as Rac and Cdc42) bind and activat
 e actin nucleation\nfactors\, which localize to discrete zones--- along th
 e membrane\ncorresponding to sites of actin polymerization and membrane\np
 rotrusions. However\, it is unclear how actin networks spatially organize\
 nsignaling proteins into clusters and how this spatial organization affect
 s\nsignal transduction. By reconstituting a Cdc42-driven signaling cascade
 \nfrom purified proteins and supported lipid bilayers\, we have gained\nme
 chanistic insights into how actin dynamics exert local feedback control\no
 n signal transduction events at the membrane.
