XIST gene

XIST gene
[X-inactivation–specific transcript] a gene, expressed only by the inactive X chromosome (see lyonization), that is responsible for the inactivation of genes on that chromosome. It does not encode a protein and is believed to function via binding of its RNA transcription product to the same X chromosome.
