Characterized natural quadruplex sequences

Construct name	Sequence (5′–3′)
4NRAS	GGGAGGGGCGGGUCUGGG
4MAPK2	GGGAGGGAGGGAGGG
5CHST2	GGGCGGGUUGGGUCGGGUCGGG
6PCGF2	GGGAUGGGAGGGAGGGAGGGAAGGG

Sequences of naturally occurring 5′-UTR G-quadruplex motifs were named according to the gene they belong to and prefixed with total number of ‘GGG’-repeat runs (4, 5 or 6) in the sequence. Additional prefix of ‘con’ is used to describe the respective motif control wherein U is inserted instead of G (underlined).
