虽然只有一个Atg4存在于酵母中,但在人类和小鼠中有四个Atg4同源物,具有不同的底物特异性和催化效率。分子Atg4是一种类型的半胱氨酸蛋白酶,并且已知其在Atg8家族蛋白质可以缀合至磷脂之前的切割中的关键作用,以及在缀合的Atg8分子从膜的切割中的关键作用,该过程被称为去缀合。这两个过程都是自噬体生物合成最大效率所必需的。因此,Atg4可能是干预自噬过程的靶点。因此,重要的是测量Atg 4活性以确定和调节自噬功能。本文综述了人类Atg 4蛋白酶的催化功能和调控机制,并详细讨论了Atg 4活性的分析方法。
While only one Atg4 is present in yeast, there are four Atg4 homologues in human and in mouse with different substrate specificities and catalytic efficiencies. The molecule Atg4 is a type of cysteine protease, and is known for its crucial roles in cleavage of the Atg8 family proteins before they can be conjugated to phospholipids, and also in cleavage of the conjugated Atg8 molecules from the membrane, a process known as deconjugation. Both processes are required for the maximal efficiency in autophagosome biogenesis. Atg4 could thus be a target for intervention of the autophagy process. It is thus important to measure Atg4 activity to determine and to modulate the autophagy function. Here we review the catalytic functions and regulatory mechanisms of human Atg4 proteases, and discuss the methodology for analyzing Atg4 activity in details.
