Bidirectional transport on a dynamic lattice

TL;DR

This paper investigates how dynamic lattice structures influence bidirectional molecular motor transport, revealing a transition to more efficient transport as large clusters dissolve due to lattice dynamics.

Contribution

It introduces a study of lattice dynamics effects on bidirectional transport, highlighting a transition to efficient transport not seen in static lattice models.

Findings

Lattice dynamics can dissolve large clusters in bidirectional transport.

Transport efficiency improves with certain types of lattice dynamics.

A transition point exists where cluster dissolution enhances transport efficiency.

Abstract

Bidirectional variants of stochastic many particle models for transport by molecular motors show a strong tendency to form macroscopic clusters on static lattices. Inspired by the fact that the microscopic tracks for molecular motors are dynamical, we study the influence of different types of lattice dynamics on stochastic bidirectional transport. We observe a transition toward efficient transport (corresponding to the dissolution of large clusters) controlled by the lattice dynamics.
