Purified Cenp-C was mixed with either the Kmn1-Mis12-Nnf1a or Kmn1-Mis12-Nnf1b trimer, and interaction was assessed by gel filtration and analytical centrifugation.

Interaction in vitro; proteins produced as a recombinant fusion proteins in bacterial system.

Cenp-C can bind either the Kmn1-Mis12-Nnf1a or Kmn1-Mis12-Nnf1b trimer to form a complex that is 76.4 kDa or 75.6 kDa in size, respectively.

Purified Cenp-C was mixed with either the Kmn1-Mis12-Nnf1a or Kmn1-Mis12-Nnf1b trimer, then purified by gel filtration. The complex was then treated with BS2G bi-functional crosslinking reagent, and cross-links were mapped by mass spectrometry.
