In molecular biology, ghrelin opposite strand (non-protein coding), also known as GHRLOS, is a long non-coding RNA. It is antisense to the GHRL gene, which encodes ghrelin. In humans, it is located on chromosome 3p25. It is alternatively spliced into multiple isoforms. [3] [4]
An exon is any part of a gene that will form a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing. The term exon refers to both the DNA sequence within a gene and to the corresponding sequence in RNA transcripts. In RNA splicing, introns are removed and exons are covalently joined to one another as part of generating the mature RNA. Just as the entire set of genes for a species constitutes the genome, the entire set of exons constitutes the exome.
An intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product. The word intron is derived from the term intragenic region, i.e., a region inside a gene. The term intron refers to both the DNA sequence within a gene and the corresponding RNA sequence in RNA transcripts. The non-intron sequences that become joined by this RNA processing to form the mature RNA are called exons.
Alternative splicing, or alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to code for multiple proteins. In this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene. This means the exons are joined in different combinations, leading to different (alternative) mRNA strands. Consequently, the proteins translated from alternatively spliced mRNAs usually contain differences in their amino acid sequence and, often, in their biological functions.
In molecular biology, small nucleolar RNAs (snoRNAs) are a class of small RNA molecules that primarily guide chemical modifications of other RNAs, mainly ribosomal RNAs, transfer RNAs and small nuclear RNAs. There are two main classes of snoRNA, the C/D box snoRNAs, which are associated with methylation, and the H/ACA box snoRNAs, which are associated with pseudouridylation. SnoRNAs are commonly referred to as guide RNAs but should not be confused with the guide RNAs that direct RNA editing in trypanosomes or the guide RNAs (gRNAs) used by Cas9 for CRISPR gene editing.
Probable ATP-dependent RNA helicase DDX5 also known as DEAD box protein 5 or RNA helicase p68 is an enzyme that in humans is encoded by the DDX5 gene.
Probable ATP-dependent RNA helicase DDX17 (p72) is an enzyme that in humans is encoded by the DDX17 gene.
Interferon alpha-inducible protein 27 is a protein that in humans is encoded by the IFI27 gene.
BTB/POZ domain-containing protein 1 is a protein that in humans is encoded by the BTBD1 gene.
High affinity cGMP-specific 3',5'-cyclic phosphodiesterase 9A is an enzyme that in humans is encoded by the PDE9A gene.
Natural antisense transcripts (NATs) are a group of RNAs encoded within a cell that have transcript complementarity to other RNA transcripts. They have been identified in multiple eukaryotes, including humans, mice, yeast and Arabidopsis thaliana. This class of RNAs includes both protein-coding and non-coding RNAs. Current evidence has suggested a variety of regulatory roles for NATs, such as RNA interference (RNAi), alternative splicing, genomic imprinting, and X-chromosome inactivation. NATs are broadly grouped into two categories based on whether they act in cis or in trans. Trans-NATs are transcribed from a different location than their targets and usually have complementarity to multiple transcripts with some mismatches. MicroRNAs (miRNA) are an example of trans-NATs that can target multiple transcripts with a few mismatches. Cis-natural antisense transcripts (cis-NATs) on the other hand are transcribed from the same genomic locus as their target but from the opposite DNA strand and form perfect pairs.
DNA directed RNA polymerase II polypeptide J-related gene, also known as POLR2J2, is a human gene.
6C RNA is a class of non-coding RNA present in actinomycetes. 6C RNA was originally discovered as a conserved RNA structure having two stem-loops each containing six or more cytosine (C) residues. Later work revealed that 6C RNAs in Streptomyces coelicolor and Streptomyces avermitilis have predicted rho-independent transcription terminators, and microarray and reverse-transcriptase PCR experiments indicate that the S. coelicolor version is transcribed as RNA. Transcription of the S. coelicolor RNA increases during sporulation, and three transcripts were detected that overlap the 6C motif, but have different apparent start and stop sites.
Nuclear Enriched Abundant Transcript 1 (NEAT1) is a ~3.2 kb novel nuclear long non-coding RNA. It is also known as Virus Inducible NonCoding RNA (VINC) or MEN epsilon RNA. It is transcribed from the multiple endocrine neoplasia locus.
PtaRNA1 is a family of non-coding RNAs. Homologs of PtaRNA1 can be found in the bacterial families, Betaproteobacteria and Gammaproteobacteria. In all cases the PtaRNA1 is located anti-sense to a short protein-coding gene. In Xanthomonas campestris pv. vesicatoria, this gene is annotated as XCV2162 and is included in the plasmid toxin family of proteins.
MALAT 1 also known as NEAT2 is a large, infrequently spliced non-coding RNA, which is highly conserved amongst mammals and highly expressed in the nucleus. MALAT1 was identified in multiple types of physiological processes, such as alternative splicing, nuclear organization, epigenetic modulating of gene expression, and a number of evidences indicate that MALAT1 also closely relate to various pathological processes, ranging from diabetes complications to cancers. It regulates the expression of metastasis-associated genes. It also positively regulates cell motility via the transcriptional and/or post-transcriptional regulation of motility-related genes. MALAT1 may play a role in temperature-dependent sex determination in the Red-eared slider turtle.
In molecular biology, GNAS antisense RNA , also known as GNAS-AS1, is a long non-coding RNA.It is antisense to the GNAS gene. It is an imprinted gene, expressed only from the paternal allele, suggesting that it may have a role in suppression of the paternal NESP55 allele encoded by GNAS.
In molecular biology, NPPA antisense RNA 1, also known as NPPA-AS1 is a long non-coding RNA. It is an antisense transcript of the NPPA gene, which encodes the precursor of cardiodilatin-related peptide and atrial natriuretic factor. NPPA-AS1 is alternatively spliced. At least one isoform of NPPA-AS1 can regulate the expression of spliced and unspliced variants of NPPA, possibly by the formation of duplexes with NPPA mRNA.
De novo transcriptome assembly is the de novo sequence assembly method of creating a transcriptome without the aid of a reference genome.
Chimeric RNA, sometimes referred to as a fusion transcript, is composed of exons from two or more different genes that have the potential to encode novel proteins. These mRNAs are different from those produced by conventional splicing as they are produced by two or more gene loci.
Single nucleotide polymorphism annotation is the process of predicting the effect or function of an individual SNP using SNP annotation tools. In SNP annotation the biological information is extracted, collected and displayed in a clear form amenable to query. SNP functional annotation is typically performed based on the available information on nucleic acid and protein sequences.
