Summary Information
Automatically generated summary See sections below for more information	The gene iab-4 is referred to in FlyBase by the symbol Dmel\iab-4 (CR31271, FBgn0020546). It is a non_protein_coding_gene from Drosophila melanogaster. Its molecular function is unknown. The biological processes in which it is involved are not known. 7 alleles are reported. The phenotypes of these alleles are annotated with: ovary; pole cell; adult abdominal segment 1; testis; adult abdominal segment 5; adult abdominal segment 2; oviduct; adult abdominal segment 4. It has 2 annotated transcripts. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of extremely low expression. Peak expression observed within 00-12 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: No FlyAtlas data available because no Affy2 ProbeSet aligns to an exon of iab-4. Comments on Affy2 ProbeSet: No relevant information because no Affy2 ProbeSet aligns to an exon of iab-4. Gene sequence location is 3R:12675726..12682219.

Additional comments	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) The "iab-4" locus produces two microRNAs, represented by "mir-iab-4". (Ronshaugen et al., 2005)
Other Comments
	New annotation (CR31271) in release 3 of the genome annotation. (FlyBase Genome Annotators, 2002-2003) The transcription unit that produces the noncoding iab-4 transcript has been identified. (Lewis et al., 1995) Non-coding RNA regulating abd-A. (Martin et al., 1995)
