Subject: RhoL and DRac3 To whom it may concern, We have become aware of an error in Flybase that is due to our own mistake and we would like to correct it to prevent confusion. The gene known as RhoL, which we cloned and published (Murphy and Montell, JCB 1996, v. 133, pp617-630) was incorrectly mapped to 67C on polytene chromosomes. This gene is identical in sequence to a gene that has been named Rac3 and which has been localized to 85D. We believe that the 85D localization is correct and the 67C localization is incorrect. We apologize for the error and hope that you can correct the Flybase entries as soon as possible. Sincerely, Denise Montell
