GHRLOS transcripts that extend over 1.4 kb of the promoter region and 106 nucleotides of exon 4 of the ghrelin gene(GHRL) initiate 4.8 kb downstream of the terminal exon 4 of GHRL and are present in the 3' untranslated exon of the adjacent gene TATDN2 (TatD DNase domain containing 2). The 3' region of GHRLOS is also antisense, in a tail-to-tail fashion to a novel terminal exon of the neighbouring SEC13 gene, which is important inprotein transport. GHRLOS that is riddled with stop codons is little nucleotide and amino-acid sequence conservation between vertebrates. The gene spans 44 kb on 3p25.3, is extensively spliced and harbours multiple variable exons<ref name="ref1" />.

GHRLOS RNA transcripts display several distinctive features of non-coding (ncRNA) genes, including 5' capping, polyadenylation, extensive splicing and short open reading frames<ref name="ref1" />.
 +
GHRLOS natural antisense transcripts, functioning as a non-coding RNA,may regulate one or both of these genes, because GHRLOS overlaps the terminal exons of both GHRL andSEC13-T<ref name="ref1" />
 +
 
 +
===Expression===
 +
We have also investigated the expression of GHRLOS and found evidence of differential tissue expression. It is highly expressed in tissues which are emerging as major sites of non-coding RNA expression (the thymus, brain, and testis), as well as in the ovary and uterus. In contrast, very low levels were found in the stomach where sense, GHRL derived RNAs are highly expressed.
 +
For non-quantitative RT-PCR analysis of GHRLOS splicing, RT-PCRs were performed with a forward primer in a region common to the 5' terminal exon Ia/b and a reverse primer in the 3' terminal exon 4 of GHRLOS<ref name="ref1" />.

GHRLOS, which gives rise to endogenous ghrelin natural antisense transcripts. exhibits features which are common to many non-coding RNA genes, including extensive splicing, lack of significant and conserved open reading frames, differential expression and lack of conservation in vertebrates.

Annotated Information

Name

GHRLOS:ghrelin opposite strand/antisense RNA(HGNC nomenclature)

"GHRL antisense RNA 1 (non-protein coding)", GHRL-AS1, NCRNA00068, "non-protein coding RNA 68"[1]

Characteristics

Mapping of GHRLOS transcript 5' and 3' ends.[1]

GHRLOS transcripts that extend over 1.4 kb of the promoter region and 106 nucleotides of exon 4 of the ghrelin gene(GHRL) initiate 4.8 kb downstream of the terminal exon 4 of GHRL and are present in the 3' untranslated exon of the adjacent gene TATDN2 (TatD DNase domain containing 2). The 3' region of GHRLOS is also antisense, in a tail-to-tail fashion to a novel terminal exon of the neighbouring SEC13 gene, which is important inprotein transport. GHRLOS that is riddled with stop codons is little nucleotide and amino-acid sequence conservation between vertebrates. The gene spans 44 kb on 3p25.3, is extensively spliced and harbours multiple variable exons[1].

Function

GHRLOS RNA transcripts display several distinctive features of non-coding (ncRNA) genes, including 5' capping, polyadenylation, extensive splicing and short open reading frames[1]. GHRLOS natural antisense transcripts, functioning as a non-coding RNA,may regulate one or both of these genes, because GHRLOS overlaps the terminal exons of both GHRL andSEC13-T[1]

Expression

We have also investigated the expression of GHRLOS and found evidence of differential tissue expression. It is highly expressed in tissues which are emerging as major sites of non-coding RNA expression (the thymus, brain, and testis), as well as in the ovary and uterus. In contrast, very low levels were found in the stomach where sense, GHRL derived RNAs are highly expressed. For non-quantitative RT-PCR analysis of GHRLOS splicing, RT-PCRs were performed with a forward primer in a region common to the 5' terminal exon Ia/b and a reverse primer in the 3' terminal exon 4 of GHRLOS[1].
