Scientists discover new gene expression mechanism with possible role in human disease

(University of North Carolina Health Care) When cells grow and divide to ensure a biological function, DNA must be unwound from its typical tightly packed form and copied into RNA to create proteins. When this process goes awry, the result could be diseases such as cancers. University of North Carolina School of Medicine researchers have discovered that a protein called Spt6 facilitates RNA degradation so that cells have just the right amount of RNA for the creation of proteins.
