Ftx (gene)

In molecular biology, FTX transcript, XIST regulator (non-protein coding), also known as FTX (Five prime to Xist), is a long non-coding RNA. In humans, it is located on the X chromosome. It was identified during sequence analysis of the X inactivation centre, surrounding the XIST gene. FTX contains several microRNAs within its introns. It upregulates expression of XIST, and inhibits DNA methylation of the XIST promoter.
