Spatial distribution of cytoskeleton-mediated feedback controls cell polarization: a computational study

|
By Parijat Banerjee, Jonathan Kuhn, Dhiman Sankar Pal, Yu Deng
| BioRxiv
Abstract In the social amoeba Dictyostelium, cell motility is regulated through a signal transduction excitable network that interfaces with the cytoskeleton to control actin polymerization patterns. In turn, the cytoskeleton influences the signaling machinery via several feedback loops, but the nature and function of this feedback remain poorly understood.

PIP5K-Ras bistability initiates plasma membrane symmetry breaking to regulate cell polarity and migration

|
By Yu Deng, Tatsat Banerjee, Dhiman Sankar Pal, Parijat Banerjee
| BioRxiv
Abstract Symmetry breaking, polarity establishment, and spontaneous cell protrusion formation are fundamental but poorly explained cell behaviors. Here, we demonstrate that a biochemical network, where the mutually inhibitory localization of PIP5K and Ras activities plays a central role, governs these processes. First, in resting cells devoid of cytoskeletal activity, PIP5K is uniformly elevated on the plasma membrane, while Ras activity remains minimal.
