Caenorhabditis elegans gene cyn-9, encoding CYclophiliN, peptidyl-prolyl cis-trans isomerase.
SUMMARY back to top
[Wormbase] cyn-9 encodes a peptidyl prolyl cis-trans isomerase most similar to human cyclophilin G (OMIM:606093); CYN-9 likely functions as a catalyst in the folding and modification of cuticle collagens; a cyn-9::lacZ reporter is expressed in the syncytial hypodermis from early larval through adult stages; cyn-9 mRNA is expressed most strongly at the mid-L3 and mid-L4 larval stages, the intermoult period when collagens are synthesized.
Wormbase predicts one model

AceView synopsis, each blue text links to tables and details
According to AceView, this gene is well expressed, 1.4 times the average gene in this release, in embryos, L3 and L4 larvae, and adult [Kohara cDNAs]. See the in situ hybridization pattern in Kohara NextDB. The sequence of this gene is defined by 6 cDNA clones and 12 elements defined by RNA-seq, some from embryo (seen once), mixed (once).
The gene contains 5 distinct gt-ag introns. Transcription produces one mRNA. Variant a is transpliced to SL2, SL3. There are 2 validated alternative polyadenylation sites (see the diagram).
Function: There are 3 articles specifically referring to this gene in PubMed. In addition we point below to 2 abstracts. Proteins are expected to localize in nucleus. No phenotype has yet been reported to our knowledge: this gene's in vivo function is yet unknown.
The spliced mRNA putatively encodes a good protein, containing Peptidyl-prolyl cis-trans isomerase, cyclophilin-type domain [Pfam].

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.
