Membrane fission during bacterial spore development requires DNA-pumping driven cellular inflation

A. Landajuela, M. Braun, A. Martinez-Calvo, C. D. A. Rodrigues, C. Gomis Perez, T. Doan, D. Z. Rudner, N. S. Wingreen, E. Karatekin

This study shows that DNA-pumping driven forespore inflation generates membrane tension required for FisB-mediated membrane fission during bacterial spore development.

Rapid propagation of membrane tension at a presynaptic terminal

C. Gomis Perez, N. R. Dudzinski, M. Rouches, B. Machta, D. Zenisek, E. Karatekin

The paper shows membrane tension propagates rapidly in neuronal terminals but not in chromaffin cells, affecting exo-endocytosis coupling.

The neuronal calcium sensor Synaptotagmin-1 and SNARE proteins cooperate to dilate fusion pores

Z. Wu, N. Dharan, Z. A. McDargh, S. Thiyagarajan, B. O'Shaughnessy, E. Karatekin

This study shows Synaptotagmin-1 promotes fusion pore dilation by reorienting SNARE complexes through calcium-induced C2 domain insertion, enhancing neurotransmitter and hormone release.

FisB relies on homo-oligomerization and lipid-binding to catalyze membrane fission in bacteria

A. Landajuela, M. Braun, C. D. A. Rodrigues, A. Martinez-Calvo, T. Doan, F. A. Horenkamp, A. Andronicos, V. Shteyn, N. D. Williams, C. Lin, N. S. Wingreen, D. Z. Rudner, E. Karatekin

This study identifies that FisB catalyzes bacterial membrane fission through homo-oligomerization and lipid-binding, without requiring curvature sensing or lipid microdomains.
