1H, 13C, 15N and 31P chemical shift assignments of a human Xist RNA A-repeat tetraloop hairpin essential for X-chromosome inactivation

Initiation of X-chromosome inactivation in female mammals depends on the non-coding RNA Xist. We have solved the NMR structure of a 14-nucleotide hairpin with a novel AUCG tetraloop fold from a Xist A-repeat that is essential for silencing. The 1H, 13C, 15N and 31P chemical shift assignments are reported.
