Abstract

The N-terminal domain of hnRNP A1 protein, termed UP1, comprises two tandem RNA-recognition motifs, both of which are necessary for efficient RNA binding and for the alternative splicing activity of hnRNP A1. Recombinant human UP1 expressed in E. coli has been crystallized in space group P21 with unit-cell dimensions a = 37.94, b = 43.98, c = 55.64 Å and β = 93.9°. The unit-cell volume is consistent with one UP1 molecule per asymmetric unit and a calculated 49% solvent content. The crystal diffraction limit is higher than 1.3 Å, and a data set to 2.0 Å has been collected. Diffraction data from one platinum and two mercury derivatives have also been collected.
