The N-terminus of CENP-T proteins interacts directly with the Ndc80 complex in the outer kinetochore. Importantly, the CENP-T-W complex does not directly associate with CENP-A, but with histone H3 in the centromere region. CENP-T and -W form a hetero-tetramer with CENP-S and -X and bind to a ~100 bp region of nucleosome-free DNA forming a nucleosome-like structure. The DNA-CENP-T-W-S-X complex is likely to be associated with histone H3-containing nucleosomes rather than with CENP-nucleosomes. This domain is the C-terminal histone fold domain of CENP-T, which associates with chromatin [2-3].

It is also found in the final part of the middle domain of various FACT (facilitates chromatin transactions) complex subunits, such as Spt16 and either Pob3 (yeast) or the related SSRP1 (higher eukaryotes). This domain plays a role in DNA binding [2-4].
