Subject: Helping FlyBase: ADRC-10330 Dear David, We are currently curating the abstracts for the upcoming 42nd (Washington, D.C.) Annual Drosophila Research Conference, for FlyBase. I am writing in connection with your abstract: 'necrotic mutations homologous to disease-associated varients in human serpins.' You mention a gene that is new to FlyBase, Spn43Ad. Do you know which of the Genome Project CG annotations your gene corresponds to? All the CGs have corresponding gene records in FlyBase already and we don't like to make duplicate records for what is actually the same gene unless we can't avoid it. If your gene does not correspond to a CG then perhaps you could tell me its map location, as this is valuable information for the genome annotation project. Thank you for your help, with best wishes, Rachel. Subject: Re: Helping FlyBase: ADRC-10330 Rachel, 43Ad is a serpin in the 43A cluster that we missed from our sequencing or cDNAs. It was clear as a transcript between 43Ab and 43Ac, ie within the 5' pk intron. We have a projectile working on it, who hopefully will have the cDNA fully sequenced soon. At first sight it looks like a non-inhibitory serpin. We will let you have full details soon. David Gubb Department of Genetics University of Cambridge Downing Street CB2 3EH UK
