Summary
[Wormbase] cps-6 encodes an ortholog of human mitochondrial endonuclease G (EndoG) that promotes apoptosis, and is required to degrade nicked (TUNEL-positive) DNA in apoptotic cells; transgenic CPS-6 is localized to mitochondria, but transgenic CPS-6 lacking a mitochondrial localization sequence is found in nuclei, and nuclei may be the in vivo target of CPS-6 after its activation by CED-3; CPS-6 has magnesium-dependent nuclease activity in vitro; cps-6(sm116) and cps-6(RNAi) animals have delayed CED-3-induced apoptosis, and cps-6(sm116) suppresses a constitutively active ced-3 transgene; cps-6(sm116) can be transgenically rescued by mouse EndoG; CPS-6 binds WAH-1 (an apoptosis-inducing factor ortholog) in vitro, WAH-1 binding enhances CPS-6's endonuclease activity, and constitutive transgenic coexpression of cps-6 with wah-1 induces cell death not seen with constitutive expression of either cps-6 or wah-1 alone; CPS-6 binds CRN-1 (a flap endonuclease ortholog) in vitro, and may form a large complex in vivo with CRN-1, CRN-4, CRN-5, CYP-13, and WAH-1; CRN-1 enhances CPS-6's endonuclease activity in vitro, CPS-6 enhances CRN-1's gap-dependent endonuclease and 5'-3' exonuclease activities, and cps-6 is required for excess cell deaths induced by a crn-1 transgene.
Wormbase predicts one model.

According to AceView, this gene is well expressed, 1.3 times the average gene in this release, from L1 larvae to adult [Kohara cDNAs]. The expression profile for the gene, derived from the proportion of animals at each stage in each Kohara library is: embryos 1%, L1 or L2 larvae 58%, L3 to adult 39%. See the in situ hybridization pattern in Kohara NextDB. The sequence of this gene is defined by 7 cDNA clones and 10 elements defined by RNA-seq, some from l1 (seen 2 times), l2 (2), l4 (once). We annotate structural defects or features in 4 cDNA clones.
The gene contains 4 distinct gt-ag introns. Transcription produces one mRNA. Variant a is transpliced to SL1, SL2, SL3, SL4, SL5, SL6. 347 bp of this gene are antisense to spliced gene eif-3.H, raising the possibility of regulated alternate expression. Function: There are 6 articles specifically referring to this gene in PubMed. In addition we point below to 3 abstracts. This gene is associated to a phenotype (CED-3 Protease Suppressor). Functionally, the gene has been proposed to participate in a process (DNA degradation in apoptosis). Proteins are expected to have molecular functions (endonuclease activity, nucleic acid binding activity) and to localize in cytoplasm. This protein appears to interact with another protein (WAH-1). The gene interacts with 6 other genes (2K881+CRN-3, CED-3, CED-4, CED-8, CRN-1, CRN-2).
The spliced mRNA putatively encodes a good protein, containing DNA/RNA non-specific endonuclease domain [Pfam], a vacuolar domain [Psort2].

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 .
