2LA5 - PubMed Abstract: 
We have determined the solution structure of the complex between an arginine-glycine-rich RGG peptide from the human fragile X mental retardation protein (FMRP) and an in vitro-selected guanine-rich (G-rich) sc1 RNA. The bound RNA forms a newly discovered G-quadruplex separated from the flanking duplex stem by a mixed junctional tetrad ...
