The Nicotinic Acetylcholine Receptor and its Pentameric Homologs: Toward an Allosteric Mechanism of Signal Transduction at the Atomic Level
Marco Cecchini; Pierre-Jean Corringer; Jean-Pierre Changeux
<jats:p> The nicotinic acetylcholine receptor has served, since its biochemical identification in the 1970s, as a model of an allosteric ligand-gated ion channel mediating signal transition at the synapse. In recent years, the application of X-ray crystallography and high-resolution cryo–electron microscopy, together with molecular dynamic simulations of nicotinic receptors and homologs, have opened a new era in the understanding of channel gating by the neurotransmitter. They reveal, at atomic resolution, the diversity and flexibility of the multiple ligand-binding sites, including recently discovered allosteric modulatory sites distinct from the neurotransmitter orthosteric site, and the conformational dynamics of the activation process as a molecular switch linking these multiple sites. The model emerging from these studies paves the way for a new pharmacology based, first, upon the occurrence of an original mode of indirect allosteric modulation, distinct from a steric competition for a single and rigid binding site, and second, the design of drugs that specifically interact with privileged conformations of the receptor such as agonists, antagonists, and desensitizers. Research on nicotinic receptors is still at the forefront of understanding the mode of action of drugs on the nervous system. </jats:p><jats:p> Expected final online publication date for the Annual Review of Biochemistry , Volume 93 is June 2024.

A Life of Translocations
Tom A. Rapoport
<jats:p> Writing a career retrospective for this prestigious series is a huge challenge. Is my story really of that much interest? One thing that is different about my life in science is the heavy influence of the turmoil of the past century. Born in the US, raised in East Germany, and returning to the US relatively late in life, I experienced research under both suboptimal and privileged conditions. My scientific story, like the political winds that blew me from one continent to the next, involved shifts into different fields. For advice to young scientists, I would suggest: Don't be afraid to start something new, it pays to be persistent, and science is a passion. In addition to telling my own story, this article also provides the opportunity to express my gratitude to my trainees and colleagues and to convey my conviction that we have the best job on earth. </jats:p><jats:p> Expected final online publication date for the Annual Review of Biochemistry , Volume 93 is June 2024.

Lipid Quality Control and Ferroptosis: From Concept to Mechanism
Zhipeng Li; Mike Lange; Scott J. Dixon; James A. Olzmann
<jats:p> Cellular quality control systems sense and mediate homeostatic responses to prevent the buildup of aberrant macromolecules, which arise from errors during biosynthesis, damage by environmental insults, or imbalances in enzymatic and metabolic activity. Lipids are structurally diverse macromolecules that have many important cellular functions, ranging from structural roles in membranes to functions as signaling and energy-storage molecules. As with other macromolecules, lipids can be damaged (e.g., oxidized), and cells require quality control systems to ensure that nonfunctional and potentially toxic lipids do not accumulate. Ferroptosis is a form of cell death that results from the failure of lipid quality control and the consequent accumulation of oxidatively damaged phospholipids. In this review, we describe a framework for lipid quality control, using ferroptosis as an illustrative example to highlight concepts related to lipid damage, membrane remodeling, and suppression or detoxification of lipid damage via preemptive and damage-repair lipid quality control pathways. </jats:p><jats:p> Expected final online publication date for the Annual Review of Biochemistry , Volume 93 is June 2024.
