Optogenetic activation of RhoA reveals a direct mechanism for local septin recruitment. The findings show that RhoA signaling—not myosin contractility—drives septin remodeling in interphase cells.

Spotlight: Williams et al. (https://t.co/gxNEUUspOG) show that chromosome segregation is independent of separase-mediated feedback and that synchrony is affected by a small number of stochastic effects. Boland @Biologie_UNIGE discusses the findings: https://t.co/xoXqXyObR7

New research from Lee, Higgs et al. @GeiselMed shows how #INF2, a key #actin regulator, is activated by calcium-calmodulin and free actin monomers. Actin-binding proteins like profilin and thymosin aren't just helpers - they directly tune INF2 activity. https://t.co/ZYPcpXmC4S

This study presents new tools for measuring the intracellular calcium concentration close to transmitter release sites, which may be relevant for synaptic vesicle fusion and replenishment.
