Subject: ADRC: 545C Dear Katsuhiko and Hideyuki, I am writing in connection with your abstract for the upcoming Washington DC ADRC: 'Drosophila paired-like homeobox gene expressed in the subsets of developing neurons and epidermis.' You describe unc-4, a gene new to FlyBase. Do you have a cytological location for unc-4? It is nice if we can keep as many gene records anchored to the map as possible. Thank you for your help, with best wishes, Rachel. PS: Katsuhiko's email address is not in FlyBase, so I'm sending it to both of you at Hideyuki's address. Subject: Re: ADRC: 545C Dear Rachel, Thank you for your e-mail. We are happy to announce the cytological location on the FlyBase, as a new g ene. The cytological location for Drosophila unc-4 is 16D1-2. Yours sincerely, Hideyuki Okano and Katsuhiko Tabuchi \**************************** Hideyuki Okano, M.D., Ph.D. Professor Department of Neuroanatomy Biomedical Research Center Osaka University Medical School 2-2 Yamadaoka, Suita, Osaka 565 Japan
