The sterol regulatory element-binding factor-2 (SREBF2) gene is a bifunctional locus encoding SREBP-2, a well-known transcriptional regulator of genes involved in cholesterol biosynthesis, and microRNA-33a, which has recently been shown to reduce expression of proteins involved in export of cholesterol and β-oxidation of fatty acids, thus adding an unexpected layer of complexity and fine-tuning to regulation of lipid homeostasis.
固醇调节元件结合蛋白-2(SREBF2)基因是一个具有双重功能的基因座,编码 SREBP-2,它是胆固醇生物合成相关基因的一种众所周知的转录调节剂,以及 microRNA-33a,最近的研究表明它可以降低胆固醇输出和脂肪酸β氧化相关蛋白的表达,从而为脂质稳态的调节增加了一个意想不到的复杂和精细的层面。
