Molecular motor traffic with a slow binding site

We discuss how the presence of a slow binding site in molecular motor traffic gives rise to defect-induced traffic jams that have properties different from those of the well-studied boundary-induced jams that originate from an imbalance between initiation and termination. To this end we analyze in detail the stationary distribution of a lattice gas model for traffic of molecular motors with a defect. In particular, we obtain analytically the exact spatial distribution of motors, the probability distribution of the random position of the molecular traffic jam and we report unexpected spatial anticorrelations between local molecular motor densities near the defect.

Automated summary

This study discusses how the presence of a slow binding site in molecular motor traffic leads to defect-induced traffic jams, which are different from boundary-induced jams. By analyzing a lattice gas model, the authors obtained the exact spatial distribution of motors, probability distribution of random position of traffic jam, and reported unexpected spatial anticorrelations near the defect.
