SND1 has gained importance because it is overexpressed in aggressive cancer cells and diverse primary tumors. Indeed, it is regarded as a marker of cancer malignity. A broad range of molecular functions and the participation in many cellular processes have been attributed to SND1, mostly related to the regulation of gene expression. An increasing body of evidence points to a relevant relationship between SND1 and lipid metabolism. In this review, we summarize the knowledge about SND1 and its molecular and functional relationship with lipid metabolism. We highlight that SND1 plays a direct role in the regulation of cholesterol metabolism by affecting the activation of sterol response element-binding protein 2 (SREBP2) and we propose that that might have implications in the response of lipid homeostasis to stress situations.
