Polyglutamine repeats play key role in functional development of cells

Variable polyglutamine repeats in the DNA tune the function of the protein in which they reside, scientists report. To date, these repeats were known only to cause severe neurodegenerative diseases such as Huntington’s. These findings now show that polyglutamine repeats may be more than just harmful elements. Moreover, this study lays the foundation for future research into the role of repeats in the emergence and evolution of novel functions and life forms. —> Read More
