AceView synopsis, each blue text links to tables and details
According to AceView, this gene is expressed at very high level, 7.7 times the average gene in this release, at all stages of development [Kohara cDNAs]. The expression profile for the gene, derived from the proportion of animals at each stage in each Kohara library is: embryos 25%, L1 or L2 larvae 10%, L3 to adult (including dauer) 64%. See the in situ hybridization pattern in Kohara NextDB. The sequence of this gene is defined by 28 cDNA clones and 74 elements defined by RNA-seq, some from mixed (seen 11 times), embryo (10), l2 (2), l1 (once).
The gene contains 3 distinct gt-ag introns. Transcription produces one spliced mRNA, 1 alternatively spliced variant and 1 unspliced form. Variant a is transpliced to SL4, SL2, SL3, SL5, SL1, SL7, b to SL2, SL3, SL5, SL7. There are 3 validated alternative polyadenylation sites (see the diagram).
Function: There are 4 articles specifically referring to this gene in PubMed. This essential gene is associated to a phenotype (DumPY : shorter than wild-type, Embryonic Lethal, Larval arrest, STerile Progeny, various morphological defects, shared oogenic and spermatogenic protein copurified with chromatin). This protein appears to interact with another protein (LST-3).
Protein coding potential: The spliced mRNAs putatively encode a good protein, containing Mov34/MPN/PAD-1 domain [Pfam], a coiled coil stretch [Psort2]. The remaining mRNA variant (unspliced; partial) appears not to encode a good protein.

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.
