2022年11月10日 · 发现敲除FDX1基因(该基因编码的蛋白可以将二价铜离子转化为毒性更强的一价铜离子)以及六个脂酰化蛋白质基因(LIPT1、DLD、LIAS、DLAT、PDHA1、PDHB)可以挽救铜离子对细胞的杀伤作用。 FDX1 是蛋白质脂酰化的上游调节因子; 蛋白质脂酰化是一种高度保守的赖氨酸翻译后修饰,已知仅在四种酶上发生,所有这些酶都涉及调节碳进入TCA循环的代谢复合物。 铜直接结合并诱导脂酰化DLAT的寡聚化; 从细胞裂解物中纯化了DLAT和 DLST,发 …
Here we show that FDX1 directly regulates protein lipoylation by binding the lipoyl synthase (LIAS) enzyme promoting its functional binding to the lipoyl carrier protein GCSH and not through indirect regulation of cellular Fe-S cluster biosynthesis.
Protein lipoylation: mitochondria, cuproptosis, and beyond
2024年8月1日 · Recent studies indicate that the ferredoxin 1 (FDX1)/ lipoic acid synthase (LIAS) axis links lipoylation and excessive copper ions and plays a key role in cuproptosis. New techniques suggest there are more potential lipoylated proteins.
