Subject: Helping FlyBase: ADRC-65 Dear Jessica, We are curating the abstracts for the upcoming Bellevue (Seattle) Annual Drosophila Research Conference, for FlyBase. I am writing (this time) in connection with your abstract: 'Actin-mediated changes in cell shape coordinate the timing of Drosophila photoreceptor differentiation.' You mention a gene that is new to FlyBase, acu. Do you have a map location for acu? This is a data class we like to track. Another abstract, number 441B: Act-up regulates actin organisation and cell polarity in Drosophila. B. Baum 1, Z. Wills 2, D. Van Vactor 2, N. Perrimon 1. 1) Dept Genetics, HHMI, Harvard Medical Sch, Boston, MA; 2) Dept Cell Biology, Harvard Medical Sch, Boston, MA. also mentions acu, is this the same acu as yours? Thank you for your help, with best wishes, Rachel. Subject: Helping FlyBase: ADRC-600B Dear Jessica, (Pittsburgh) Annual Drosophila Research Conference, for FlyBase. I am writing in connection with your abstract: 'blind spot is required for progression of differentiation across the Drosophila eye disc.' You mention a gene that is new to FlyBase, blind spot. Do you have a map location for blind spot? This is a data class we like to track. Unfortunately bls (the symbol you would like to use for blind spot) is already in use (bls: bractless, FBgn0028643). The symbol 'bli' is however available - would you like to use that for blind spot instead? Thank you for your help, with best wishes, Rachel. Subject: Re: Helping FlyBase: ADRC-65 Dear Rachel, The map position of acu is 21F1-2 - it is the same gene studied by Norbert Perrimon's lab, and encodes a homologue of yeast cyclase associated protein. The map position of blind spot is 78A2, and I can switch to the abbreviation bli.
