Research Abstract |
Musashi1 (Msi1) is a neural protein that suppresses translation of target mRNAs and contributes in maintenance of cell stemness and tumorigenesis. We have determined the RNA recognition mechanism by Msi1. Minimal RNA sequence for Msi1, and the binding mechanism of Msi1 that we have elucidated would provide important clues to discover new target genes for Msi1. Meanwhile, we have determined the structure of PABP and identified its Msi1 binding sites. Finally, we have prepared a protocol for building protein and nucleic acid complex models that would support the structural analysis of translational repression complex.
