Ribonucleoprotein RNP motif

The RNP motif is also referred to as RNP consensus sequence (RNP-CS), RNA binding domain (RBD), or RNA recognition 

Examples of high resolution structures of RNA in complex with a ligand RNP1 

The best characterized RNP motif in complex with RNA, is the U1A protein bound to its cognate small nuclear U1 RNA hairpin. U1A binds a 10-nucleotide hairpin structure. Different regions of the protein serve specialized functions in the interaction. The RNA hairpin is positioned on UlA by electrostatic interactions between the phosphate backbone of the RNA helix, and arginines and ly-
