Pearling in cells: A clue to understanding cell shape
Roy Bar-Ziv, Tsvi Tlusty, Elisha Moses +2
Gradual disruption of the actin cytoskeleton induces a series of structural shape changes in cells leading to a transformation of cylindrical cell extensions into a periodic chain…
Molecular Model of the Contractile Ring
D. Biron, E. Alvarez-Lacalle, Tsvi Tlusty +1
We present a model for the actin contractile ring of adherent animal cells. The model suggests that the actin concentration within the ring and consequently the power that the ring…
High-Fidelity DNA Sensing by Protein Binding Fluctuations
Tsvi Tlusty, Roy Bar-Ziv, Albert Libchaber
One of the major functions of RecA protein in the cell is to bind single-stranded DNA exposed upon damage, thereby triggering the SOS repair response.We present fluorescence anisot…
Protein-DNA computation by stochastic assembly cascade
Roy Bar-Ziv, Tsvi Tlusty, Albert Libchaber
The assembly of RecA on single-stranded DNA is measured and interpreted as a stochastic finite-state machine that is able to discriminate fine differences between sequences, a basi…
Messenger RNA Fluctuations and Regulatory RNAs Shape the Dynamics of Negative Feedback Loop
María Rodríguez Martínez, Jordi Soriano, Tsvi Tlusty +2
Single cell experiments of simple regulatory networks can markedly differ from cell population experiments. Such differences arise from stochastic events in individual cells that a…
