Lipid nanodisc scaffold and size alters the structure of a pentameric ligand-gated ion channel

V. Dalal, M. J. Arcario, J. T. Petroff, N. M. Dietzen, M. J. Rau, J. A. J. Fitzpatrick, G. Brannigan, W. W. L. Cheng

This study shows that different lipid nanodisc scaffolds and sizes alter the structure of the pentameric ligand-gated ion channel ELIC, with larger nanodiscs promoting more activated conformations.

Structural mechanism of leaflet-specific phospholipid modulation of a pentameric ligand-gated ion channel

J. T. Petroff, N. M. Dietzen, E. Santiago-McRae, B. Deng, M. S. Washington, L. J. Chen, K. T. Moreland, Z. Deng, M. Rau, J. A. Fitzpatrick, P. Yuan, T. T. Joseph, J. Henin, G. Brannigan, W. W. Cheng

The paper shows phosphatidylglycerol stabilizes the open state of ELIC by binding to a specific outer leaflet site, identified through structural and functional analyses.

Polyunsaturated fatty acids inhibit a pentameric ligand-gated ion channel through one of two binding sites

N. M. Dietzen, M. J. Arcario, L. J. Chen, J. T. Petroff, K. Krishnan, G. Brannigan, D. F. Covey, W. W. Cheng

This study identifies two fatty acid binding sites in ELIC and shows that DHA selectively inhibits the channel by binding to a specific site in the agonist-bound state.

Direct Binding of Phosphatidylglycerol at Specific Sites Modulates Desensitization of a Pentameric Ligand-Gated Ion Channel

A. Tong, J. T. Petroff, F.-F. Hsu, P. A. Schmidpeter, C. M. Nimigean, L. Sharp, G. Brannigan, W. W. Cheng

The paper shows that phosphatidylglycerol binds to and stabilizes the pentameric ligand-gated ion channel ELIC, reducing desensitization.
