Distribution of motors on growing microtubules. (A–C) Motor densities on growing MTs according to Eq. 7. Shaded areas correspond to different time points (at t = 0, MTs have zero length and there are no motors bound). In all panels: α = 4 μm−1 min−1, β = 4 min−1, and vg = 8 μm/min. (A) The value vm = 11 μm/min, assuming that motors reaching the end of the MT do not accumulate but dissociate. (B) The value vm = 3 μm/min. (C) The vm = 0 μm/min.
