摘要:

法尼酯X受体(farnesoid X receptor,FXR)是一种由胆汁酸激活的核受体,参与调控胆汁酸、脂肪、葡萄糖和氨基酸代谢相关的基因表达,FXR活性受到多种翻译后修饰方式的调控。常见FXR翻译后修饰方式包括O-糖基化、磷酸化、乙酰化、SUMO化和甲基化等,这些翻译后修饰方式可能影响FXR结合DNA和配体、异源二聚化和亚细胞定位等功能,可能特异性调控下游基因转录表达。不同翻译后修饰可导致FXR稳定性及生物学功能改变,与疾病的发生密切相关。本文拟对近5年FXR的翻译后修饰方式及参与疾病调控的机制作一综述,探讨翻译后修饰方式对FXR生理学功能的影响,为以FXR为靶点的机制研究提供理论依据。

Abstract:

Farnesoid X receptor (FXR) is a nuclear receptor activated by bile acid that is involved in regulating gene expression related to bile acid, fat, glucose, and amino acid metabolism. The activity of FXR is regulated by a variety of post-translational modifications. Common post-translational modifications of FXR include O-GlcNAcylation, phosphorylation, acetylation,sumoylation, methylation, etc. These post-translational modifications may affect FXR binding of DNA and ligand, heterodimerization, and subcellular localization, and may specifically regulate downstream gene transcription and expression. Different post-translational modifications can lead to changes in FXR stability and biological function, which are closely related to the occurrence of diseases.This paper aims to review the post-translational modification of FXR in the past five years and the mechanisms involved in disease regulation, to explore the effects of post-translational modification on the physiological function of FXR and to provide a theoretical basis for mechanism research targeting FXR.

Key words: FXR, O-glycosylation, phosphorylation, acetylation, sumoylation, methylation
