Gene or accession: CG17868 Release: 3 Gene annotation error Gene CG17868 has incorrect exon/intron structure or translation start site. Comments: The correct full-length transcript is PB. I don't understand what the evidence for PA is, and since it removes the long second exon it encodes a protein without 7TM domains that is unlikely to be a functional receptor. Unfortunately the PA form comes up as the default version of the gene, which I think is misleading.
