This study investigates protein nucleic acid interactions between various proteins and G quadruplex (GQ) forming messenger RNAs (mRNAs) in human neurological disorders. GQ structures are formed in DNA/RNA, when four guanine residues form planar tetrads stabilized by Hoogsteen base pairing, that stack forming a GQ structure stabilized by potassium ions. These GQ structures are targeted by the arginine-glycine-glycine (RGG) repeat domain containing RNA-binding domain.
Three RGG domain containing RNA-binding proteins, all of which have been implicated in neurological disorders, and their interactions with GQ forming mRNAs, were investigated in this study: fused in sarcoma (FUS), fragile X mental retardation protein …
