Proteasome Dismantles Amyloid Protein (IMAGE) University of California - San Diego Caption This is a diagram of the barrel shaped structure found in every cell called the proteasome, which chops proteins into pieces that can be resused or discarded. Yang's group showed that amyloid beta is dismantled by the proteasome and in the process outcompetes other proteins. Credit Yang Lab, UCSD Usage Restrictions For use in news reports of this finding.
