Summary
[Wormbase] hlh-3 encodes a basic helix-loop-helix transcription factor homologous to Drosophila Achaete-scute; in vitro, HLH-3 can heterodimerize, and bind an E-box-containing probe, with HLH-2, the C. elegans E/daughterless ortholog with which it is coexpressed in the nuclei of embryonic neuronal precursors.
Wormbase predicts one model.

According to AceView, this gene is expressed at very high level, 6.3 times the average gene in this release. The sequence of this gene is defined by 6 cDNA clones and 77 elements defined by RNA-seq, some from embryo (seen once).
The gene contains 1 gt-ag intron. Transcription produces one mRNA. Variant a is transpliced to SL1. Function: There are 3 articles specifically referring to this gene in PubMed. In addition we point below to 5 abstracts. This gene is associated to a phenotype. Functionally, the gene has been proposed to participate in a process (regulation of transcription). Proteins are expected to have molecular function (transcription regulator activity) and to localize in various compartments (mitochondrion, nucleus). This protein appears to interact with another protein (HLH-2). The gene interacts with 2 other genes (CES-1, HLH-2).
The spliced mRNA putatively encodes a good protein, containing Basic helix-loop-helix dimerisation region bHLH domain [Pfam].

This diagram shows in true scale the gene on the genome, the mRNAs and the cDNA clones.
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. Read more...
Mouse over the ending of each transcript gives tissues from which the supporting cDNAs were extracted. Details on tissue of origin for each intron and exon is available from the intron and exons table.
Click on any transcript to open the specific mRNA page, to see the exact cDNA clone support and eventual SNPs and to get details on tissues, sequences, mRNA and protein annotations. Proteins supported by a single continuous cDNA sequence lead to underlining the name/ending of the variant. Names not underlined result from cDNA concatenation in the coding region and should be experimentally checked.
Introns are depicted by broken lines; the height of the top of each intron reflects the relative number of clones supporting this intron. ]^[ A pink broken line denotes an intron with standard boundaries (gt-ag or gc-ag) that is exactly supported (i.e. a cDNA sequence exactly matches the genome over 16 bp, 8 on both sides of the intron). ] ^ ] A blue broken line denotes non-standard introns, exactly supported, but with non-standard at-ac or any other boundaries. ]-[ Pink and ] - ] blue straight lines represent 'fuzzy' introns of the standard and non-standard types respectively, those introns do not follow the 16 bp rule. Black straight lines ]-[denote gaps in the alignments.
Exons: Wide filled pink areas represent putative protein coding regions, narrow empty pink boxes represent the 5'UTR (on the left) and 3' UTR (on the right). Flags identify validated endings: cap site on the 5' side, polyadenylation site on the 3' side. Filled flags correspond to frequent events while empty flags have lesser supporting cDNAs (yet all are validated); at the 3' side, black flags are associated to the main AATAAA signal, blue flags to any single letter variant of the main .
