Figure 4. — Close-up of the Dam1 : Ndc80c contacts. (a) Interactions between the Dam1 α-helical segment (cyan) and Ndc80 : Nuf2 (red and orange, respectively). Serine residues 257, 265 and 292 that are targets for phosphorylation by Ipl1/Aurora B are shown in yellow. The side chain of Ser257 is close to conserved Ndc80 glutamate 276 and its phosphorylation would result in electrostatic repulsion. (b) Interactions between the Dam1 extended segment (cyan) and Ndc80 : Nuf2 (red and orange, respectively). Note the salt bridge between conserved Dam1 residue Arg299 and Ndc80 Asp295.
