## Abstract

Transcription factor EB (TFEB) plays a crucial role in lipid metabolism and is indispensable for maintaining intracellular metabolic homeostasis. Its functionality relies significantly on its subcellular localization and transcriptional activity. Recent studies have revealed that SUMOylation regulates the subcellular localization and transcriptional activity of TFEB. Numerous studies indicate that mutations or dysfunctions of TFEB SUMOylation sites, as vital regulatory mechanisms, are closely associated with lipid metabolism in cardiovascular disease. Thus, in this review, we provide an overview of the current knowledge and recent advances in TFEB SUMOylation, with a particular focus on the mechanism of TFEB SUMOylation and its role in lipid metabolism, providing potential new strategies for developing novel therapeutic treatments for cardiovascular diseases.
