EMD entries 4917 and 4918 (motor and tail domain reconstructions of human dynein-2 complex) were docked into a subtomogram average of IFT complex B and inhibited dynein-1b in anterograde IFT trains from C. reinhardtii cilia (EMD-4303) using Chimera's 'Fit in Map' command. The two DHC2 bundles connecting the tail and motor domain were modelled using SWISS-MODEL and RaptorX Contact (deposition as UNK).
