title: Analysis of expression of hybrid yeast genes containing ARS elements.
abstract: In an attempt to devise a new assay for ARS-binding proteins we have inserted the HO ARS between the upstream activation site and the TATA region of the yeast CYC1 promoter. A marked reduction in promoter activity is observed. Inactivation of the HO ARS element by point mutation does not restore promoter activity to its original level, although a modest activation is seen. We have also inserted the HO ARS into the intron of the yeast actin gene; although there is no apparent deleterious effect on transcription, the activity of the ARS is abolished in this new environment.
