Human gene RFP2 is a candidate tumor suppressor located at 13q14.3 and deleted in multiple tumor types. To explore regulation of RFP2, we determined structure of the 5′-untranslated region of RFP2 gene and its promoter. RFP2 promoter area is TATA-less, highly enriched in G and C nucleotides, and contains multiple quadruplex forming GGGGA-repeats. Deletion analysis of 5′-flanking sequences demonstrated that repeat containing fragment possesses activity seven times exceeding that of the combined SV40 promoter/enhancer. Other unusual features of the RFP2 promoter include anomalously high electrostatic fields induced by sequence-dependent dipoles and very low nucleosome forming potential. A “minimized” version of the RFP2 promoter could be used for overexpression of the various transgenes in the mammalian cells.
