Fragile X tremor/ataxia syndrome (FXTAS) is a recently recognized condition, which is actually one of the most prevalent heritable neurodegenerative diseases. It is assumed that the condition is caused by deficiency for the protein Pur-alpha, which is essential for normal neural function. Structural studies undertaken by a team under the leadership of Dr. Dierk Niessing of the Helmholtz Zentrum München and the Gene Center at Ludwigs-Maximilians-University (LMU) have now determined the three-dimensional structure of Pur-alpha, and gained insights into the molecular function of the protein. The findings provide a possible basis for the development of an effective therapy for the disease.(PNAS Early Edition, 21. Oktober 2009)
