Researchers reveal secret of key protein in brain and heart function

Brown University biologists have solved the structure of a critical piece of synapse-associated protein 97 (SAP97) found in abundance in the heart and head, where it is believed to play a role in everything from cardiac contractions to memory creation. Results are published in The Journal of Biological Chemistry.
