Background Information
Insulin-induced genes (INSIGs), which consist of two isoforms (INSIG1 and INSIG2), are representative endoplasmic reticulum (ER)-resident oxysterol-binding proteins (OSBPs). INSIG1 is part of negative regulatory feedback, acting as a brake on SREBP transcriptional function (PMID: 23919961). INSIG1 also has a secondary function mediating sterolaccelerated proteolytic degradation of HMG CoA reductase, thus impacting the mevalonate pathway. Suppression of INSIG1 function promotes hepatic lipid remodelling and restrains NASH (non-alcoholic steatohepatitis) progression(PMID: 33722690).
