Schematic representation of the competition phenomenon among multi-copy promoters.
PICs, transcription pre-initiation complexes; TSS, transcription start site of the Ser1 promoter; orange arrows represent transcription activity and transcription orientation of RLuc; 2×, 3× and 4× of Ser1 represent 2, 3 and 4 copies of the Ser1 proximal promoter, respectively; RLuc, renilla luciferase; SV40, 3′-untranslated sequences.
