Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
Source for identity of: lncRNA:sphinx sphinx
The sphinx gene appears to have been formed by the insertion of a retroposed sequence of the ATP synthase F-chain gene from chromosome 2 (CG4692) into the 102F region of chromosome 4, recruiting sequences upstream to form a new locus.
The "sphinx" gene (AF479655) had mistakenly been associated with the CG11091 annotation in FlyBase. This was in error, since the CG11091 annotation is on the opposite strand to the "sphinx" gene. A new annotation corresponding to "sphinx", CR34154, has been created in release 5.1 of the genome annotation.
The sphinx gene on the 4th chromosome appears to be a chimeric gene, with the second exon having all the hallmarks of a retrosequence derived from the CG4692 gene on the 2nd chromosome. In addition, the retroposition process appears to have involved an S-element, leaving a partial S-element fragment attached the CG4692-derived region in the sphinx gene. The retrosequence has recruited a nearby exon and intron in the 4th chromosome, thereby evolving a chimeric gene structure.
The "sphinx" gene is a young chimeric RNA gene and is named "sphinx" to invoke an analogy to another chimera, the Sphinx from ancient Greek legend having a lion's body and a human head.
