AMP-activated protein kinase (AMPK) is a highly conserved cellular energy sensor that plays a central role in metabolic homeostasis. A recent study in Science (Egan et al., 2011) identifies ULK1 as a substrate for AMPK phosphorylation, a modification required for selective autophagy of mitochondria and cell survival during starvation.
腺苷酸活化蛋白激酶（AMPK）是一种高度保守的细胞能量感受器，在代谢稳态中起着核心作用。最近发表在《科学》杂志上的一项研究（Egan 等人，2011 年）确定 ULK1 是 AMPK 磷酸化的底物，这种修饰对于饥饿时线粒体的选择性自噬和细胞存活是必需的。
