Gene or accession: CG9907 Gene annotation error Gene CG9907 has incorrect exon/intron structure. Comments: para, CG9907 Celera sequence: AE003502; AAF48617 Celera have mispredicted a splice site and when corrected translation is a match for the sequence from Thackeray and Ganetzky, J. Neurosci. 14:2569-2578 (1994), U26713- U26717. Celera have annotated the longest isoform but there are known to be 29 isoforms having different combinations of optional exons A, B, C, D, E and F. There is also some evidence of optional exons H and I from sequence similarity to D. virilis. I have not annotated all these in Swiss-prot, no idea if you want to!
