Subject: ADRC-292C and 3W Dear Mark, We are currently curating the abstracts for the upcoming Bellevue (Seattle) Annual Drosophila Research Conference, for FlyBase. I am writing in connection with your abstract: 'Immunolocalization, structural studies, and genetic analysis of the Sep2 septin.' and 'The septin proteins of Drosophila: their roles in cytokinesis and other processes.' You mention two genes that are new to FlyBase, Sep4 and Sep5. Do you have map locations for Sep4 and Sep5? 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: Sep4 and Sep5 Dear Rachel, Mark Peifer asked me to respond to your inquiry regarding Sep4 and Sep5 (abstracts 292C and 3W). Sep4 has been characterized by Nick Brown and colleagues and is in 15A1-2. You should confirm that with Nick and cite him for the information. I have characterized Sep5 and found by P1 hybridization and P element insertion analysis that it is in 43F. Regards, Karen
