Polypurine tract
WebJan 1, 2005 · The polypurine tract of the VEGF promoter region contains a guanine-rich sequence consisting of four runs of three or more contiguous guanines separated by one or more bases. This guanine-rich sequence conforms to a general motif capable of forming an intramolecular G-quadruplex: G x N y G x N y G x N y G x, where x ≥ 3 and y ≥ 1 ( 28, 29).
