SUMMARY back to top
Summary
[Wormbase] dpf-5 encodes a putative acylamino-acid-releasing enzyme (AARE; EC 3.4.19.1), orthologous to human APEH, with no obvious function in mass RNAi assays.
Wormbase predicts one model, 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 3 spliced variants

AceView synopsis, each blue text links to tables and details
Expression: According to AceView, this gene is expressed at high level, 3.8 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 11%, L1 or L2 larvae 40%, L3 to adult 49%. See the in situ hybridization pattern in Kohara NextDB. The sequence of this gene is defined by 40 cDNA clones and 10 elements defined by RNA-seq, some from l1 (seen 14 times), l2 (7), mixed (7), embryo (5), l4 (4). We annotate structural defects or features in one cDNA clone.
Alternative mRNA variants and regulation: The gene contains 8 distinct gt-ag introns. Transcription produces 3 alternatively spliced mRNAs. Variant a is transpliced to SL1, SL2, SL3, SL4, SL7, SL8, SL5. There are 2 probable alternative promotors (see the diagram). The mRNAs appear to differ by overlapping exons with different boundaries.
Function: There is one article specifically referring to this gene in PubMed. Functionally, the gene has been proposed to participate in a process (proteolysis and peptidolysis). Proteins are expected to have molecular function (serine-type peptidase activity) and to localize in cytoplasm. These proteins appear to interact with another protein (VPS-2).
Protein coding potential: The 3 spliced mRNAs putatively encode good proteins, altogether 3 different isoforms (1 complete, 1 COOH complete, 1 partial), some containing Peptidase S9, prolyl oligopeptidase active site region domain [Pfam].

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.
