FIGURE 4. The pseudoautosomal region, which fully escapes inactivation on the Xi, exhibits a striking 11 fold enrichment in the GATA repeat sequence.

FIGURE 4

Right) Shows the distribution of GATA repeats (and CTAT) along the X chromosome determined by word count analysis, and a close-up view of the pseudoautosomal and XE region that escapes inactivation (yellow). Importantly, small repeats of (GATA)n were widely dispersed at very many sites throughout this ~10 Mb segment, and were not found in large blocks. Left) DNA FISH using a GATA DNA oligo probe labels the pseudoautosomal region of the X-chromosome strongly, confirming that it is unique in the genome for this striking sequence feature.
