(A) Overview from the side (left) and top (right). (B) Close-up view and interactions of DASH/Dam1c with the MT and Ndc80c. Approximate distances between the attachments of the flexible extensions on the DASH/Dam1c ring and their target sites, defined by crosslinking, are shown. Interactions A, B and C are between Ndc80c and DASH/Dam1 subunits Dam1, Ask1 and Spc34:Spc19, respectively. S. cerevisiae residues known to be phosphorylated by Ipl1/Aurora B are shown in the insets, and arrows indicate release of Ndc80c binding upon phosphorylation.
