Centromere proteins CENP-S and CENP-X are members of the constitutive centromere-associated network, which is a conserved group of proteins that are needed for the assembly and function of kinetochores at centromeres. Intriguingly CENP-S and CENP-X have alter egos going by the names of MHF1 (FANCM-associated histone-fold protein 1) and MHF2 respectively. In this guise they function with a DNA translocase called FANCM (Fanconi's anemia complementation group M) to promote DNA repair and homologous recombination. In the present review we discuss current knowledge of the biological roles of CENP-S and CENP-X and how their dual existence may be a common feature of CCAN (constitutive centromere-associated network) proteins.
