  • a Locations are with respect to the Yp1 transcription start site except where noted. DSX-A, DSX-B, and DSX-C are DNA elements that bind the DSX transcription factor (Burtis et al. 1991) and the consensus regions are shown with a line above them. Other transcription factor binding sequences are from the following: AEF-1-C/EBP (Falb and Maniatis 1992) and BBF-2 (Abel et al. 1992).
