Abstract

Proton extrusion by plasma membrane autoinhibited H⁺ ATPases (AHAs) enables stomatal opening and plant cell expansion. Takase et al. demonstrated that heterocomplexes of C5 and C7 RAF-like kinases activate AHAs. The modular nature of C5–C7 RAF complexes allows cell-type-specific responses to stimuli, such as stomatal guard-cell CO₂ levels.

raf样蛋白激酶信号模块控制植物质子泵活性。

质膜自抑制H+ atp酶（AHAs）通过质子挤压使植物气孔打开和细胞扩增。Takase等人证明C5和C7 raf样激酶的异络合物可以激活aha。C5-C7 RAF复合物的模块化特性允许细胞类型特异性响应刺激，如气孔保护细胞二氧化碳水平。

期刊介绍： For over 40 years, Trends in Biochemical Sciences (TIBS) has been a leading publication keeping readers informed about recent advances in all areas of biochemistry and molecular biology. Through monthly, peer-reviewed issues, TIBS covers a wide range of topics, from traditional subjects like protein structure and function to emerging areas in signaling and metabolism. Articles are curated by the Editor and authored by top researchers in their fields, with a focus on moving beyond simple literature summaries to providing novel insights and perspectives. Each issue primarily features concise and timely Reviews and Opinions, supplemented by shorter articles including Spotlights, Forums, and Technology of the Month, as well as impactful pieces like Science & Society and Scientific Life articles.
