Brain receptor pulls open electrical gate like a puppet master
For the first time, researchers in the lab of CSHL Professor Hiro Furukawa have been able to track each atom in the NMDA receptor, an important brain protein, as it transmits or inhibits neural signals. Critical for brain development and function, the receptor converts chemical messages between cells into electrical signals within a neuron. The key to transmitting that information is opening the receptor's built-in ion channel, a hollow pore that allows electrically charged ions to flow. Unlocking the receptor's ion channel is like working a stringed puppet—rock one part of the receptor and slender filaments pull open the channel's gate. Rock it a little differently, the filaments loosen, and the gate snaps shut. Understanding how the receptor works could lead to better treatments for Alzheimer's disease, depression, epilepsy, stroke, or schizophrenia.
