| Research Abstract |
Telomeres are specialized nucleoprotein complexes that cap the ends of eukaryotic linear chromosomes, stabilizing them and protecting their integrity. In budding yeast major telomere binding protein Rap1 controls telomere length. We prepared Rap1 and GFP fusion Rap1, and analyzed their structures by electron microscopy. Electron tomography and high resolution fluorescence microscopy revealed three-dimensional structures of unique filaments made of Rap1.
