Gene expression in growing cells: A biophysical primer
Ido Golding, Ariel Amir
Cell growth and gene expression, essential elements of all living systems, have long been the focus of biophysical interrogation. Advances in single-cell methods have invigorated t…
Design principles of transcription factors with intrinsically disordered regions
Wencheng Ji, Ori Hachmo, Naama Barkai +1
Transcription Factors (TFs) are proteins crucial for regulating gene expression. Effective regulation requires the TFs to rapidly bind to their correct target, enabling the cell to…
Conditional Probability as Found in Nature: Facilitated Diffusion
Ori Hachmo, Ariel Amir
Transcription Factors (TFs) are proteins that regulate gene expression. The regulation mechanism is via the binding of a TF to a specific part of the gene associated with it, the T…
Pressure-induced Shape-shifting of Helical Bacteria
Cesar L. Pastrana, Luyi Qiu, Shahaf Armon +2
Many bacterial species are helical in form, including the widespread pathogen H. pylori. Motivated by recent experiments on H. pylori showing that cell wall synthesis is not unifor…
Universal catastrophe time distributions of dynamically unstable polymers
Paul B. Dieterle, Jenny Zheng, Ethan Garner +1
Dynamic instability -- the growth, catastrophe, and shrinkage of quasi-one-dimensional filaments -- has been observed in multiple biopolymers. Scientists have long understood the c…
Bending Instability of Rod-shaped Bacteria
Luyi Qiu, John W. Hutchinson, Ariel Amir
A thin-walled tube, e.g., a drinking straw, manifests an instability when bent by localizing the curvature change in a small region. This instability has been extensively studied s…
