This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process. Binds preferentially to the 5'-UGCAC-3' motif in vitro.<ref>PMID:9848648</ref> | |

| - | The crystal structure of the RNA-binding domain of the small nuclear ribonucleoprotein U1A bound to a 21-nucleotide RNA hairpin has been determined at 1.92 A resolution. The ten-nucleotide RNA loop binds to the surface of the beta-sheet as an open structure, and the AUUGCAC sequence of the loop interacts extensively with the conserved RNP1 and RNP2 motifs and the C-terminal extension of the RNP domain. These interactions include stacking of RNA bases with aromatic side chains of proteins and many direct and water-mediated hydrogen bonds. The structure reveals the stereochemical basis for sequence-specific RNA recognition by the RNP domain. | ||
