title: Prolyl cis-trans Isomerization as a molecular timer in Crk signaling.
abstract: In a recent issue of Molecular Cell, use NMR to identify peptidyl-prolyl cis-trans isomerization as an autoinhibitory switch in the adaptor protein Crk, suggesting a new mechanism for controlling the rate of formation of signaling complexes.
