An octamer binding factor, POU2F1 (Oct-1) or POU2F2 (Oct-2), SP1, ZNF143 (Staf) and possibly other transcription factors bind the distal sequence element (DSE) in the promoter of the snRNA gene (Murphy et al. 1992, Strom et al. 1996, Murphy 1997, Hovde et al. 2002). These upstream transcription factors enhance subsequent binding of the SNAPc complex to the downstream proximal sequence element (PSE) of the promoter.
