Subject: update on nuclear hormone receptor nomenclature Dear curators of The FlyBase, My lab maintains the official nomenclature of nuclear hormone receptors (Cell 97: 1-20). We have recently done an important effort to re evaluate the nuclear receptor content of published animal genomes (to appear in Mol Biol Evol). In this process, we have noticed some small discrepancies between the nomenclature we use and that used in FlyBase. We would like to suggest that you add the following names as synonyms. Thank you for the wonderful job you do in maintaining FlyBase. flybase ID flybase name suggested synonyms FBgn0034012 CG16801 PNR, NR2E3 FBgn0037436 CG10296 FAX-1, NR2E5 FBgn0023546 Hr4 GRF, NR6A2 Sincerely yours, Vincent Laudet \-- Pr.
