Non-equilibrium phase transitions in tubulation by molecular motors

J. Tailleur, M. R. Evans, Y. Kafri

摘要:

已知分子马达对膜管的提取对真核细胞的运输性质起重要作用。通过研究一个通用类的模型管提取,我们发现了丰富的相图。特别是,我们表明,沿管的电机的密度可以表现出冲击,逆冲击和高原,这取决于参数,原则上可以探测实验。此外,相图表现出有趣的重入行为。

英文摘要:

The extraction of membrane tubes by molecular motors is known to play an important role for the transport properties of eukaryotic cells. By studying a generic class of models for the tube extraction, we discover a rich phase diagram. In particular we show that the density of motors along the tube can exhibit shocks, inverse shocks and plateaux, depending on parameters which could in principle be probed experimentally. In addition the phase diagram exhibits interesting reentrant behavior.
