Summary
This gene is a paternally expressed imprinted gene. Alternatively spliced transcript variants have been produced from this gene and they are all long non-coding RNAs. These variants share the same 5' exon, and their 3' exons are divergent. The 5' exon overlaps the intron 2 of the Igf2r gene on the opposite strand. The Igf2r intron 2 contains a CpG island, which is a promoter and drives the expression of this gene. This gene is responsible for silencing Igf2r, and the flanking Slc22a2 and Slc22a3 genes in the imprinted gene cluster. It regulates transcription of these genes through epigenetic modifications.

  7. Chromatin environments surrounding Xist, Airn, and Kcnq1ot1 suggest common mechanisms of PRC engagement and spreading. Our data indicate that lncRNA potency can be tightly linked to lncRNA abundance and that within lncRNA-targeted domains, PRCs are recruited to CGIs via lncRNA-independent mechanisms.

  8. Study showed that chromosome interactions between the Airn gene body and the Slc22a3 promoter are enriched on the maternal allele because Airn expression represses these interactions on the paternal allele. These interactions are not required to upregulate Slc22a3 expression on the maternal allele, indicating that they are not essential promoter- enhancer interactions; they may serve to place both loci in close promixity.

  9. In cardiomyocytes, silencing of Airn via siRNAs augmented cell death, vulnerability to cellular stress, and reduced cell migration. It also caused less binding of Igf2bp2 to other mRNAs and reduced translation of Igf2bp2 protein. Airn's binding partners were Igf2bp2 and Rpa1.

  10. Airn expression is both necessary and sufficient to silence Igf2r throughout embryonic stem cell differentiation.
    Title: Imprinted Igf2r silencing depends on continuous Airn lncRNA expression and is not restricted to a developmental window.

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.
