Abstract

The cytoskeleton of eukaryotic cells is composed of several classes of protein polymers among which neuronal microtubules (NMTs) are the most prominent. The radical control of cellular processes in NMT system, that are cell division, intracellular trafficking, cellular morphogenesis process and also energy moved from one cell to another cell with least loss of energy. We investigate the excitations of soliton with small perturbation along the protofilaments that are governed by Discrete Nonlinear Schrodinger (DNLS) equation. We study the modulational instability analysis on microtubulin system under the influence of electric field with Toda potential. We perform a complete investigation of aninfluence of Toda potential of tubulin dimers in the development of energy localization that has the form of breather-like soliton excitations in the neuronal microtubulinprotofilament. The evolution of the localized wave is expected to explore a very interesting physical phenomenon such as energy transfer mechanism in biological systems.
