Caenorhabditis elegans gene atf-7, encoding cAMP-dependent Transcription Factor-like.
SUMMARY back to top
Wormbase predicts 3 models, but Caenorhabditis elegans 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 8 spliced variants

Expression: According to AceView, this gene is expressed at very high level, 17.2 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 18%, L1 or L2 larvae 45%, L3 to adult 37%. See the in situ hybridization pattern in Kohara NextDB. The sequence of this gene is defined by 89 cDNA clones and 138 elements defined by RNA-seq, some from l1 (seen 23 times), embryo (14), l2 (14), mixed (8), l4 (4), whole animal (once). We annotate structural defects or features in 4 cDNA clones.
Alternative mRNA variants and regulation: The gene contains 11 distinct gt-ag introns. Transcription produces at least 8 alternatively spliced mRNAs. Variant b is transpliced to SL1, c to SL1, d to SL1, SL2, SL3, SL4, e to SL2, SL1, g to SL1. There are 3 probable alternative promotors and 34 validated alternative polyadenylation sites (see the diagram). The mRNAs appear to differ by truncation of the 5' end, presence or absence of 2 cassette exons, overlapping exons with different boundaries, splicing versus retention of 3 introns.
Note that mRNA .h was found in vivo, although it is a predicted target 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 d, e, g).
Function:. Functionally, the gene has been proposed to participate in a process (regulation of transcription, DNA-dependent). Proteins are expected to have molecular functions (protein dimerization activity, transcription factor activity) and to localize in nucleus.
Protein coding potential: The 8 spliced mRNAs putatively encode good proteins, altogether 7 different isoforms (6 complete, 1 COOH complete), some containing basic leucine zipper domain [Pfam], a vacuolar domain, a coiled coil stretch [Psort2].

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.
