  • Title: Dynamic concentration of motors in microtubule arrays.
    Author: Nédélec F, Surrey T, Maggs AC.
    Journal: Phys Rev Lett; 2001 Apr 02; 86(14):3192-5. PubMed ID: 11290140.
    Abstract:
    We present experimental and theoretical studies of the dynamics of molecular motors in microtubule arrays and asters. By solving a convection-diffusion equation we find that the density profile of motors in a two-dimensional aster is characterized by continuously varying exponents. Simulations are used to verify the assumptions of the continuum model. We observe the concentration profiles of kinesin moving in quasi-two-dimensional artificial asters by fluorescent microscopy and compare with our theoretical results.
