Comments on Gene Model
	miRNA(s) located within the transcribed region of this non-coding RNA gene. Rare iab-8 transcripts (0.2 percent, not annotated) may include downstream abd-A exons, as described in FBrf0218472. Probable lncRNA gene; may encode small polypeptide(s). Annotated transcripts do not represent all possible combinations of alternative exons and/or alternative promoters. Low-frequency RNA-Seq exon junction(s) not annotated. Gene model reviewed during 5.48

Additional comments	In addition to producing a miRNA (mir-iab-8) which represses abd-A expression, the 92kb iab-8 non-coding RNA has a second repressive function on abd-A expression which acts in cis, probably due to iab-8 transcription interfering with the abd-A promoter, which lies just downstream of the iab-8 poly(A) site. (Gummalla et al., 2012) Annotation CG31270 merged with annotation CR43261 in release 5.41 of the genome annotation; CG31270 corresponds to the 5' end of several isoforms of CR43261. (FlyBase Genome Annotators, 2011) Source for identity of: msa CR43261 (Celniker, 2010.11.29) The "iab-8" non-coding transcript encodes a microRNA (represented by "mir-iab-8") derived from a hairpin which is complementary to the hairpin present in the "iab-4" non-coding transcript (the hairpin in the "iab-4" transcript is represented by "mir-iab-4"). (Bender, 2008)
Other Comments
	The spliced product of the iab-8 RNA is non-coding by traditional criteria, but the possibility of small peptides cannot be rules out. In particular, exon 8 includes a potential 9 amino acid peptide, with appropriate translation and termination signals, and the coding potential for this peptide is well conserved in D. ananassae, D. pseudoobscura and D. willistoni. (Gummalla et al., 2012) The iab-8 ncRNA represses the expression of the abd-A gene in the posterior central nervous system. This repression is accomplished by two redundant mechanisms: firstly via the mir-iab-8 miRNA produced from the iab-8 transcript and secondly by a mechanism that acts only "in cis". The most likely explanation for second mechanism is that iab-8 transcription interferes with the abd-A promoter, which lies just downstream of the iab-8 poly(A) site. (Gummalla et al., 2012) New annotation (CR43261) in release 5.34 of the genome annotation. (FlyBase Genome Annotators, 2011) Annotation CG31270 restored in release 5.26 of the genome annotation. (FlyBase Genome Annotators, 2010) Annotation (CG31270) eliminated in release 5.2 of the genome annotation. (FlyBase Genome Annotators, 2007) New annotation (CG31270) in release 3 of the genome annotation. (FlyBase Genome Annotators, 2002-2003) An internal promoter has been identified in the iab-8 domain within the transvection mediating region downstream of Abd-B, which transcribes the iab-7 and iab-8 cis-regulatory DNA, including the Fab-8 insulator. (Zhou et al., 1999)
