The findings could lead to new treatments for brain injuries and neurodegenerative diseases, including Alzheimer’s and Parkinson’s. A study from MSU and Rutgers shows that cypin tags other proteins in the gaps between neurons to ensure they’re in the right places for healthy brain functioning. New research expands our understanding of how the brain protein cypin supports learning and memory. A new study names the protein cypin as the librarian that manages other proteins. MSU researchers collaborated with scientists from Rutgers University–New Brunswick to identify this previously unknown role for cypin in the communication between specialized brain cells called neurons.
