D. Comparison of the DCX binding clefts in the 13-PF and 14-PF MTs and mapping of the associated small (<0.8 Å) conformational adjustments in NDC. NN-MT lattice fragments were aligned on the indicated α2 and β2 tubulin subunits (ALIGNMENT). Deviations in tubulin are depicted with grey scale and in NDC with colour scale. Two perspectives are shown to cover all major MT-binding loops of NDC.
