Besides their role in cell mechanics and cell division they also provide enormous substrate for cellular signaling.Here we combine the normal mode analysis of microtubuleswith the electric charge density distribution model of a microtubule. We showinsilicothat each normal mode of a microtubule is accompanied with the high-frequency electro-
magnetic field which is generated by vibrational movement of the charge. Combination of normal modes gives rise to transient phenomenon which can manifest itself as a pulsed excitation propagating along a microtubule.We speculate that such pulses can play role in cell signaling because they are of different nature than pure electrostatic interaction which is screened out on frequencies of normal modes of microtubulesWorkplace Institute of Radio Engineering and Electronics Contact Petr Vacek, vacek@ufe.cz, Tel.: 266 773 413, 266 773 438, 266 773 488 Year of Publishing 2017
