Oxygen-induced chromophore degradation in the photoswitchable red fluorescent protein rsCherry

T. Y. H. Bui, E. De Zitter, B. Moeyaert, L. Pecqueur, B. Y. Srinivasu, A. Economou, M. Fontecave, L. Van Meervelt, P. Dedecker, B. Pedre

The paper investigates oxygen-induced chromophore degradation in rsCherry, identifying cleavage of the p-hydroxyphenyl ring and formation of cyclic structures as the cause of fluorescence loss.

Shigella ipaA mediates actin bundling through diffusible vinculin oligomers with activation imprint

C. M. Valencia-Gallardo, D. I. Aguilar, H. Khakzad, B. Cocom-Chan, C. Bou-Nader, C. Velours, Y. Zarrouk, C. Le Clainche, C. Malosse, D. Borges-Lima, N. Quenech'Du, B. Mazhar, S. Essid, M. Fontecave, A. Asnacios, , G. Tran Van Nhieu

This study shows that Shigella IpaA induces vinculin homo-oligomerization, leading to actin bundling and stable cell adhesion independent of force transduction.
