Identification of novel KKIP-interacting proteins. First and second principal components (PC) of integrated spectral intensities [i.e. the normalized cumulative fragment ion intensity for all significantly identified peptides from each protein [SINQ]; (Trudgian et al., 2011)] for 1520 trypanosome proteins identified in one or more immuno-purifications with YFP-labelled KKIP1-7 (without cross-linking). Previously identified kinetochore proteins (KKT and KKIP) and near-neighbors to the KKIP2,3,4,6 cluster are highlighted. Ribosomal proteins are highlighted as examples of high-abundance negative controls. Eight close neighbors tagged in this study are also indicated.
