Abstract

In this issue of Structure, Houser et al.¹ report cryoelectron microscopy (cryo-EM) structures of two atypical forms of the heterotrimeric epithelial sodium channel (ENaC) in which either a δ or a β subunit assembles with one β and one γ subunit. These structures shed light on the molecular principles that govern the assembly of distinct ENaC trimers.

上皮钠通道以有序的方式聚集：生物学不是掷骰子

在本期的《结构》杂志上，Houser等人报道了两种非典型形式的异三聚体上皮钠通道（ENaC）的冷冻电镜（cryo-EM）结构，其中δ或β亚基与一个β和一个γ亚基组装。这些结构揭示了控制不同ENaC三聚体组装的分子原理。

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.
