Sequential ChIP-seq profiles of CCAN components are nearly identical. Mapping of sequential ChIP-seq reads to α-satellite arrays (Hayden et al. 2013; Henikoff et al. 2015). A single α-satellite dimer from each array is shown, and the relative scale is the area of the indicated profile divided by the area of the D5Z1 profile, in which the numbers reflect the product of the total sequence abundance and enrichment. Because DXZ1, DYZ3, D19Z1, Xmono, and D5Z1 are not dimeric units, we chose pairs of tandem monomers as representatives.
