Subject: ADRC: 161B Dear Cheng-Hsin and Juan, I am writing in connection with your abstract for the upcoming Washington DC ADRC: 'DLDB: a protein that interacts with AP LIM domains and is required for dorsoventral compartmentalization in the wing' You mention a gene, Ldb, that is new to FlyBase. Do you have a full name or a map location for this gene? It is nice if we can keep as many gene records as possible anchored to the map. You also mention mutants -- do you have symbols for these yet? Thank you for your help, with best wishes, Rachel. Subject: Re: ADRC: 161B Hi Rachel, The map location is 60A. As for the definitive name we are waiting to do some complementation tests with alleles of a gene called Chip. Based on map location and sequence, it seems likely that Ldb is the same as Chip. However we have been unable, so far, to obtain Chip alleles from the people working on this gene. Cheers Juan Botas
