Abstract

The mitochondrial fusion protein optic atrophy 1 (OPA1) is required to maintain cristae structure and for ATP synthase assembly. Our recent work demonstrates that OPA1 dynamically regulates these processes by sensing changes in nutrient availability through mitochondrial solute carriers and adjusting the metabolic output of mitochondria accordingly. This is a critical survival process as its inhibition leads to cell death.

摘要

线粒体融合蛋白视神经萎缩蛋白1(OPA1)是维持嵴结构和ATP合酶组装所必需的。我们最近的研究表明,OPA1通过线粒体溶质载体感知营养物质可用性的变化,并相应地调整线粒体的代谢输出,从而动态调节这些过程。这是一个关键的生存过程,因为对其抑制会导致细胞死亡。
