SUMMARY back to top
RefSeq annotates one representative transcript (NM included in AceView variant.a), 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 11 spliced variants.

AceView synopsis, each blue text links to tables and details
Expression: According to AceView, this gene is expressed at high level, 1.4 times the average gene in this release. The sequence of this gene is defined by 165 GenBank accessions from 143 cDNA clones, some from lung (seen 12 times), carcinoid (6), kidney (6), liver (6), placenta (6), prostate (6), uterus (5) and 73 other tissues. We annotate structural defects or features in 27 cDNA clones.
Alternative mRNA variants and regulation: The gene contains 15 distinct introns (14 gt-ag, 1 gc-ag). Transcription produces 13 different mRNAs, 11 alternatively spliced variants and 2 unspliced forms. There are 2 probable alternative promotors, 4 non overlapping alternative last exons and 6 validated alternative polyadenylation sites (see the diagram). The mRNAs appear to differ by truncation of the 5' end, truncation of the 3' end, overlapping exons with different boundaries, splicing versus retention of 2 introns.
3 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 cAug10).
Function: There are 5 articles specifically referring to this gene in PubMed. Functionally, the gene has been proposed to participate in a process (rRNA processing). Proteins are expected to localize in various compartments (nucleus, nucleolus).
Protein coding potential: 9 spliced mRNAs putatively encode good proteins, altogether 8 different isoforms (5 complete, 1 COOH complete, 2 partial), some containing Fcf1 domain [Pfam]. The remaining 4 mRNA variants (2 spliced, 2 unspliced) appear not to encode good proteins.

RNA-seq gene expression profile across 16 selected tissues from the Non-Human Primates Reference Transcriptome Resource (link to NHPRTR project).
- Primates: Apes (HUM: Human (Illumina BodyMap 2), CHP: Chimpanzee), Old World monkeys (PTM: Pig-Tailed Macaque, JMI Japanese Macaque, RMI Rhesus Macaque Indian, RMC Rhesus Macaque Chinese, CMM Cynomolgus Macaque Mauritian, CMC Cynomolgus Macaque Chinese, BAB Olive Baboon, SMY Sooty Mangabey); New World monkeys (MST common Marmoset, SQM Squirrel Monkey, OWL Owl Monkey); and Lemurs (MLM Mouse Lemur, RTL Ring-Tailed Lemur).
- 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.
