Ftx, a conserved functional long ncRNA,which located in the cis-acting regulatory region of the imprinted X-chromosome inactivation(XCI), is a positive regulator of Xist.

Transcriptomic Nomenclature
FTX, FTX transcript, XIST regulator (non-protein coding)(HGNC nomenclature)
"five prime to XIST", FLJ33139, LINC00182 [1]
Function
Ftx is specifically upregulated during female ES cell differentiation at the onset of XCI. Loss of Ftx expression through the deletion of the promoter region leads to local alteration in the chromatin structure. More importantly, Ftx impacts on gene expression within theXic and in particular on Xist, as Xist is significantly downregulated in the absence of Ftx [1]. Disruption of Ftx did not affect the survival of female embryos or expression of Xist and other X-linked genes in the preimplantation female embryos, which indicates that Ftx is dispensable for imprinted XCI in preimplantation embryos [2]
Cellular Localization
It produces a transcript with no apparent coding potential that predominantly remains in the nucleus [1]
Expression
FTX identified as chromatin-associated lncRNA was predominantly downregulated in breast tumor [3].
Evolution
Ftx is well conserved during evolution and contains several microRNAs (miRs) which are also conserved [3]
