蛋白质N端乙酰化是真核生物蛋白质的一种重要修饰。其功能包括调节蛋白质-蛋白质相互作用和靶向膜,如少数蛋白质的研究所证明的。发现50年后,由数千种独特蛋白质携带的N-末端乙酰基的潜在一般功能仍然是个谜。然而,最近的功能数据表明N-末端乙酰化作为降解信号和作为阻止蛋白质靶向分泌途径的决定因素的作用,从而突出N-末端乙酰化作为蛋白质的生命和死亡的主要决定因素。这些贡献代表了新的和有趣的假设,将指导未来几年的研究。
Protein N-terminal acetylation is a major modification of eukaryotic proteins. Its functional implications include regulation of protein–protein interactions and targeting to membranes, as demonstrated by studies of a handful of proteins. Fifty years after its discovery, a potential general function of the N-terminal acetyl group carried by thousands of unique proteins remains enigmatic. However, recent functional data suggest roles for N-terminal acetylation as a degradation signal and as a determining factor for preventing protein targeting to the secretory pathway, thus highlighting N-terminal acetylation as a major determinant for the life and death of proteins. These contributions represent new and intriguing hypotheses that will guide the research in the years to come.
