+, protein localizes to CENIV (ChIP) and/or kinetochores (fluorescence microscopy). Recruitment of all proteins was scored by ChIP, except for Cse4p-GFP in mif2–3 and Mtw1p-GFP, Ndc80p-GFP, and Cftf19p-GFP in the Mif2p degron strain mif2td, for which recruitment was analyzed using wide-field Deltavision fluorescence microscopy (De Wulf et al., 2003). −, protein does not localize to CENIV (ChIP).
