Subject: Helping FlyBase: CSH-209 Dear Catherine, We are currently curating the abstracts for the 2001 CSH Neurobiology of Drosophila Conference, for FlyBase. I am writing in connection with your abstract: 'Drosophila F3/ Contactin is required in axonal insulation.' You mention a gene that is new to FlyBase, Cont. 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 very much for your help, with best wishes, Rachel. \---------------------------------------------------------------------- Rachel Drysdale, Ph.D. FlyBase (Cambridge), \---------------------------------------------------------------------- Subject: Re: Helping FlyBase: CSH-209 Dear Rachel Drysdale, The Drosophila gene that we have named Dcontactin correspond to CG1084. According to flybase annotations it is homologous to human TAG-1 and chick axonin-1, but according to the blasts that we have made, it is also homologous to human and mouse contactin. We have sequenced the cDNA and it encodes a protein of 1390 aa instead of the predicted 1336 aa Please tell me if you need other informations about this gene.
