Gene or accession: CG8810, Dspt4 Gene annotation error Gene Dspt4 has a mistake in the supporting evidence or functional assignment. Comments: CG8810 is annotated correctly as a gene on the (-) strand having homology to BolA protein, and is a predicted mevalonate kinase. Dspt4 is on the (+) strand annotated as the Drosophila homolog of yeast Spt4 (correct) but it is also annotated as a mevalonate kinase. The problem seems to lie in the overlapping transcription units of these genes. BDGP cDNA LD44495 (5' sequence) encodes the entire Dspt4 ORF but overlaps with 3' CK02143 and 3' GH04687. LD16567, which encodes part of CG8810, is downstream from Dspt4 on the opposite strand. Sequence data from our lab indicates that the LD44495 3' end ((+) strand) is downstream from the 5' end of LD16567 ((-) strand). Therefore the majority of CG8810 may be transcribed on the opposite strand as part of the Dspt4 transcription unit, confusing the annotation. If this explanation is unclear, please e-mail me.
