Subject: ADRC: 819B Dear Brenda and Sarah, I am writing in connection with your abstract for the upcoming Washington DC ADRC: 'Cloning and characterization of the D. melanogaster homologue of SIR2' You describe Sir2, a gene new to FlyBase. Do you have a cytological location for Sir2? 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: Brenda's email address is not in FlyBase, so I'm sending it to both of you at Sarah's address. Subject: ADRC: 819B -Reply Hi Rachel, Good to hear from you .... you guys don't waste any time do you?! The SIR2 homologue maps to position 34A on the second chromosome. I suppose I should come up with a proper name before M. Ashburner re-names it ...yes? Sarah
