    Summary
    Acts upstream of or within epigenetic maintenance of chromatin in transcription-competent conformation; inactivation of paternal X chromosome; and negative regulation of transcription by RNA polymerase II. Is expressed in several structures, including early conceptus; liver; and retina nuclear layer. Orthologous to human TSIX (TSIX transcript, XIST antisense RNA).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
