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.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 September 2026.
All research outputs
#12,344,472
of 34,360,889 outputs
Outputs from Biochemical & Biophysical Research Communications
#12,780
of 33,075 outputs
Outputs of similar age
#53,822
of 129,736 outputs
Outputs of similar age from Biochemical & Biophysical Research Communications
#107
of 254 outputs
Altmetric has tracked 34,360,889 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 33,075 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 129,736 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 254 others from the same source and published within six weeks on either side of this one. This one is in the 4th percentile – i.e., 4% of its contemporaries scored the same or lower than it.
