FACT stabilizes tailless nucleosomes. CTD and/or HMG domain(s) of SSRP1 are required for this activity. Effect of FACT-N (A) and comparison of the effects of FACT-N and FACT-N(SSRPΔ) on tailless nucleosomes (B) as detected by spFRET microscopy. Typical frequency distributions of proximity ratios (EPR) are shown. n is a number of analyzed nucleosomes.
