The current concept places between 1,500 and 16,000 effectively interbreeding individuals (census 4,500 to 48,000 individuals) within Tanzania and proximal regions.
Recent findings show that resistance to neutralization by b12 was an outcome of substitutions that resided in the region proximal to CD4 contact surface.
It is reported to interact with proteins in the proximal region of the CD5 promoter, which contains the all three regions characterized here.
This alleles if found in Africa and proximal regions of Eurasia.
But in the female the proximal region is darkened, being broadly black, though with intensive metallic reflection.
Results obtained using 4C are highly reproducible with most of the interactions that are detected between regions proximal to one another.
The proximal and distal regions intersect, producing stationary rings.
Oct-11a is located in the proximal region of mouse chromosome 9 linked to Ets-1, Thy-1 and Drd2.
Recent studies have shown that the proximal variable region specifies the trinucleotide component of the DNA target sequence.
These activators are only fully active in the context of other general transcription factors localized in the proximal region of the promoter.
