摘要

在本期《结构》杂志上，Chi 等人1 报告了结构和功能研究，揭示了拮抗剂 SG-094 对溶酶体双孔通道 TPC2 的抑制机制，这对药物开发很有意义。拮抗剂的结合会诱导电压传感器结构域 II（VSD II）向下位移，并伴随着整个通道的不对称构象重排。

Descending to inhibit: Antagonist-induced downward shift of VSD II in TPC2

In this issue of Structure, Chi et al.¹ report structural and functional studies that reveal the inhibition mechanism of the lysosomal two-pore channel TPC2 by the antagonist SG-094, which is of interest for drug development. Antagonist binding induces the downward displacement of the voltage-sensor domain II (VSD II), which is accompanied by asymmetric conformational rearrangements of the entire channel.

期刊介绍： Structure aims to publish papers of exceptional interest in the field of structural biology. The journal strives to be essential reading for structural biologists, as well as biologists and biochemists that are interested in macromolecular structure and function. Structure strongly encourages the submission of manuscripts that present structural and molecular insights into biological function and mechanism. Other reports that address fundamental questions in structural biology, such as structure-based examinations of protein evolution, folding, and/or design, will also be considered. We will consider the application of any method, experimental or computational, at high or low resolution, to conduct structural investigations, as long as the method is appropriate for the biological, functional, and mechanistic question(s) being addressed. Likewise, reports describing single-molecule analysis of biological mechanisms are welcome. In general, the editors encourage submission of experimental structural studies that are enriched by an analysis of structure-activity relationships and will not consider studies that solely report structural information unless the structure or analysis is of exceptional and broad interest. Studies reporting only homology models, de novo models, or molecular dynamics simulations are also discouraged unless the models are informed by or validated by novel experimental data; rationalization of a large body of existing experimental evidence and making testable predictions based on a model or simulation is often not considered sufficient.
