摘要

Transcription factor EB (TFEB), a member of the bHLH leucine-zipper family of transcription factors, drives the expression of autophagic and lysosomal genes [1, 2]. TFEB is localized to the cytoplasm in normal conditions and translocated to nuclear under specific conditions, such as nutrient starvation [3]. TFEB positively regulates the expression of lysosomal genes, controls lysosome population and promotes cellular degradation of lysosomal substrates [4-6]. Lysosome plays a key role in autophagic process in which autophagic substrates are degraded [7]. TFEB may link autophagy with lysosomal biogenesis via activating multiple genes encoding lysosomal proteins [8], Thus, identification of TFEB as a target regulator may provide a novel therapeutic strategy for modulating lysosomal function in human disease [9].
