GPR1-AS is a novel imprinted gene that is expressed from a paternal allele in the human placenta
GPR1-AS:GPR1 antisense RNA (HGNC nomenclature)
"G protein-coupled receptor 1 antisense RNA", GPR1AS
Epigenetic regulation mechanisms in the imprinted GPR1-GPR1AS-ZDBF2 region were well-conserved betweenhuman and mouse genomes without the high sequence conservation of the intergenic lncRNAs. LncRNAs with highly conserved epigenetic and transcriptional regulation across species arose by divergent evolution from a common ancestor, if they do not have identical exon structures.
GPR1AS/Zdbf2linc is exclusively expressed in human/mouse placenta with paternal-allele-specific expression and maternal-allele-specific promoter methylation (GPR1/Gpr1 DMR).
GPR1AS/Zdbf2linc is rarely expressed throughout post-gastrulation development and into somatic tissues due to bi-allelic hypermethylation at their transcription start sites.
