    Musashi-2 (MSI2) belongs to Musashi family of RNA binding proteins (RBP). Like Musashi-1 (MSI1), it is overexpressed in a variety of cancers and is a promising therapeutic target. Both MSI proteins contain two N-terminal RNA recognition motifs and play roles in posttranscriptional regulation of target mRNAs. Previously, we have identified several inhibitors of MSI1, all of which bind to MSI2 as well. In order to design MSI2-specific inhibitors and compare the differences of binding mode of the inhibitors, we set out to solve the structure of MSI2-RRM1, the key motif that is responsible for the binding. Here, we report the crystal structure and the first NMR solution structure of MSI2-RRM1, and compare these to the structures of MSI1-RBD1 and other RBPs. A high degree of structural similarity was observed between the crystal and solution NMR structures. MSI2-RRM1 shows a highly similar overall folding topology to MSI1-RBD1 and other RBPs. The structural information of MSI2-RRM1 will be helpful for understanding MSI2-RNA interaction and for guiding rational drug design of MSI2-specific inhibitors.
