Constitutive plasma membrane interaction of active Rho GEF Ect2 inhibits cortex contraction pulses

Kristina Mrug, Nina Schulze, Katarina Blažević…·Perihan Nalbant

This study shows that constitutive plasma membrane association of active Ect2 suppresses pulsatile Rho activity dynamics during mitosis, unlike Lbc-type GEFs.

Optogenetic stimulation of Lbc GEF-mediated Rho activity dynamics promotes cell invasion

Jessica S. Wagner, Konstantina Feller, Nicole Schrenke…·Perihan Nalbant

This study uses optogenetics to control Lbc GEF activity in melanoma cells, showing that increased Rho activity enhances contraction dynamics, spheroid expansion, and cell escape.
