Annotated Information

Approved Symbol

GNG12-AS1:GNG12 antisense RNA 1

Characteristics

GNG12-AS1 is an RNAPII Transcript with H3K36me3 Signatures of Transcribed Gene.[1]

Regulation

Neoplastic silencing of the normally active DIRAS3 allele reduces transcription of the GNG12-AS1 lncRNA in cis but does not affect its transcription on the homologous chromosome with the constitutively silent imprinted DIRAS3 allele. In addition, demethylation of a cancer cell line with loss of DIRAS3 Imprinting Leads to upregulation of DIRAS3 Expression and a Decrease in the Levels of GNG12-AS1 Transcripts.[1]

DIRAS3 and GNG12-AS1 Are Coexpressed in Several Tissues and Reduced in Breast Cancer [1].

DIRAS3 and GNG12-AS1 are coexpressed in several tissues and reduced in breast cancer. GNG12-AS1 has several splice variants, some splice variants of GNG12-AS1 are allele specific, all of which initiate from a single transcription start site. In placenta tissue and normal cell lines, GNG12-AS1 is biallelically expressed but some isoforms are allele-specifically spliced.[1]
