Gene or accession: CG7437 Release: 2 Gene annotation error Gene CG7437 has incorrect exon/intron structure. Comments: The present GenBank annotation for the scaffold segment, AE003596.2, places the 5' end of the mub mRNA (CT122869) at position 32,648. However, cDNA analyses show that the 5' end actually maps 27 kb upstream of this. A published cDNA analysis (Grams & Korge (1998) Gene 215: 191-201; sequence accession X99340) maps the 5' end at AE003596.2 position 4930 and reports a 5' exon corresponding to AE003596.2 4930-5238. Furthermore, the BDGP EST LD32520 for the mub gene has a similar 5' exon which extends slightly farther upstream, AE003596.2 4926-5238. Two P elements in the BFD are inserted in this 5' exon, EP(3)3623 and EP(3)3108. The P element l(3)00386 is inserted 54 nt upstream of this 5' exon.
