p62/多价螯合体-1/A170/ZIP(以下简称p62)是一种支架蛋白,具有多种功能,如信号转导、细胞增殖、细胞存活、细胞死亡、炎症、肿瘤发生和氧化应激反应。虽然p62是一种自噬底物并通过自噬降解,但p62作为自噬受体用于选择性自噬清除蛋白质聚集体和细胞器。此外,p62作为各种信号传导途径的信号传导中心,包括NF-κB、Nrf 2和mTOR。本文综述了p62在肝脏中的病理生理作用,包括肝包涵体的形成、胆汁淤积、肥胖、胰岛素抵抗、肝细胞死亡和肿瘤发生等。
p62/sequestosome-1/A170/ZIP (hereafter referred to as p62) is a scaffold protein that has multiple functions, such as signal transduction, cell proliferation, cell survival, cell death, inflammation, tumorigenesis, and oxidative stress response. While p62 is an autophagy substrate and is degraded by autophagy, p62 serves as an autophagy receptor for selective autophagic clearance of protein aggregates and organelles. Moreover, p62 functions as a signaling hub for various signaling pathways, including NF-κB, Nrf2 and mTOR. In this review, we discuss the pathophysiological role of p62 in the liver, including formation of hepatic inclusion bodies, cholestasis, obesity, insulin resistance, liver cell death and tumorigenesis.
