Subject: ADRC: 404B Dear Kerrie-Ann and John, I am writing in connection with your abstract for the upcoming Washington DC ADRC: 'Positional cloning of DTS7, encoding a proteasome beta-type subunit.' You describe 'Su(DTS)-1', a gene that is new to FlyBase. Do you have a symbol or a cytological location for Su(DTS)-1? It is nice if we can keep as many gene records as possible anchored to the map. Thank you for your help, with best wishes, Rachel. Subject: Re: ADRC: 404B Dear Rachel, Su(DTS)-1: this is a dominant suppressor of the dominant temperature-sensitive lethal mutants, DTS5 (also known as Pros26 or l(3)73Ai1) and DTS7. These DTS mutants both encode altered proteasome subunits. We are currently trying to characterize this gene more thoroughly, and we don't have a good cytological position of it yet, but by recombination mapping it maps at 3-48.5, just to the right of pink. I hope this info suffices. John
