Mutate Or Die: New Polymerase Gives Desperate Yeast An Option

...ras in humans. His laboratoryis now searching for counterparts in humans to the two genes that code for zeta, and scientist Peter Gibbs has found onewhose sequence bears the markings of a zeta polymerase. If zeta is found in humans and works similarly, it would be anattractive target for anti-cancer therapies. ...

Single Mechanism Seen To Underlie Group Of Neurodegenerative Diseases: Mutant Proteins Form Insoluble Masses In The Nuclei Of Neurons

... new anddangerous characteristic that their normal counterparts do not. In some neurons,the CAG-repeat proteins accumulate in the nuclei of the cells, aggregating intoinsoluble masses that can crowd and eventually fill much of the nuclear space.And once this aggregation has begun, the mutant proteins appear to re...
