| - | The essential splicing factors SF1 and U2AF play an important role in the recognition of the pre-mRNA 3' splice site during early spliceosome assembly. The structure of the C-terminal RRM (RRM3) of human U2AF(65) complexed to an N-terminal peptide of SF1 reveals an extended negatively charged helix A and an additional helix C. Helix C shields the potential RNA binding surface. SF1 binds to the opposite, helical face of RRM3. It inserts a conserved tryptophan into a hydrophobic pocket between helices A and B in a way that strikingly resembles part of the molecular interface in the U2AF heterodimer. This molecular recognition establishes a paradigm for protein binding by a subfamily of noncanonical RRMs. | ||
