SUMMARY back to top
RefSeq annotates 2 representative transcripts (NM included in AceView variants .b and .d), but Homo sapiens cDNA sequences in GenBank, dbEST, Trace and SRA, filtered against clone rearrangements, coaligned on the genome and clustered in a minimal non-redundant way by the manually supervised AceView program, support at least 20 spliced variants.

AceView synopsis, each blue text links to tables and details
Note that this locus is complex: it appears to produce several proteins with no sequence overlap.
Expression: According to AceView, this gene is expressed at high level, 3.7 times the average gene in this release. The sequence of this gene is defined by 427 GenBank accessions from 383 cDNA clones, some from tongue, tumor tissue (seen 51 times), uterus (27), lung (22), brain (16), skin (12), trachea (9), amelanotic melanoma, cell line (8) and 103 other tissues. We annotate structural defects or features in 9 cDNA clones.
Alternative mRNA variants and regulation: The gene contains 26 distinct gt-ag introns. Transcription produces 21 different mRNAs, 20 alternatively spliced variants and 1 unspliced form. There are 4 probable alternative promotors, 5 non overlapping alternative last exons and 4 validated alternative polyadenylation sites (see the diagram). The mRNAs appear to differ by truncation of the 5' end, truncation of the 3' end, presence or absence of 12 cassette exons, overlapping exons with different boundaries, splicing versus retention of 3 introns.
5 variants were isolated in vivo, despite the fact that they are predicted targets of nonsense mediated mRNA decay (NMD).
Efficacy of translation may be reduced by the presence of a shorter translated product (uORF) initiating at an AUG upstream of the main open reading frame (in variant dAug10, gAug10, hAug10).
Function: There are 54 articles specifically referring to this gene in PubMed. Functionally, the gene has been tested for association to diseases (Alcoholism; Attention Deficit Disorder with Hyperactivity; Autistic Disorder; Bipolar Disorder; Breast Neoplasms; Drug Toxicity; Edema; Genetic Predisposition to Disease; Mental Disorders; Schizophrenia) and proposed to participate in processes (anterior/posterior pattern formation, bone morphogenesis, embryonic eye morphogenesis, embryonic hindlimb morphogenesis, epithelium development, Harderian gland development, negative regulation of cell proliferation, negative regulation of transcription from RNA polymerase II promoter, positive regulation of apoptosis, positive regulation of programmed cell death, positive regulation of transcription from RNA polymerase II promoter, prostate gland epithelium morphogenesis, regulation of transcription, DNA-dependent, reproductive structure development, trachea cartilage development). Proteins are expected to have molecular functions (DNA binding, metal ion binding, retinoic acid receptor activity, retinoid X receptor binding, sequence-specific DNA binding, steroid hormone receptor activity, transcription factor activity, zinc ion binding) and to localize in various compartments (mitochondrion, nucleus, transcription factor complex). Putative protein interactors have been described (DMWDANDDMPK, HMGA1, ITGB1BP2, JUBANDHAUS4, MAP6, NCOA1, NCOA3, NCOR1, NCOR2, NR0B2, PNRC1, PNRC2, RXRA, RXRB, RXRG, SMAD3, SRF, USHBP1ANDNR2F6).
Protein coding potential: 18 spliced mRNAs putatively encode good proteins, altogether 18 different isoforms (12 complete, 4 COOH complete, 2 partial), some containing domains Ligand-binding domain of nuclear hormone receptor, Zinc finger, C4 type (two domains) [Pfam]. The remaining 3 mRNA variants (2 spliced, 1 unspliced; 1 partial) appear not to encode good proteins.
Isoform RARG.jAug10 is annotated using as Met a Kozak-compatible a..GTG. start, thereby gaining 149 amino acids N-terminal to the first AUG. Finally proteins from this gene may be modulated by acetylation; phosphorylation, as detailed at PhosphoSite.

- The level for significantly expressed genes is color coded in 8 equal sized bins (light to dark green). Light gray is for weak not-accurately measured expression (2 to 8 reads above intergenic background); dark gray for no expression or no sequence conservation (0 read in gene). The plot to the right shows the distribution of measured expression values in all tissues for all genes (blue) and for this gene (green), in Magic index = log2(1000 sFPKM).

Compact gene diagram back to top
Alternative mRNAs are shown aligned from 5' to 3' on a virtual genome where introns have been shrunk to a minimal length. Exon size is proportional to length, intron height reflects the number of cDNAs supporting each intron, the small numbers show the support of the introns in deep sequencing (with details in mouse-over) . Introns of the same color are identical, of different colors are different. 'Good proteins' are pink, partial or not-good proteins are yellow, uORFs are green. 5' cap or3' poly A flags show completeness of the transcript.
