This gene encodes an endoplasmic reticulum membrane protein that regulates cholesterol metabolism, lipogenesis, and glucose homeostasis. The encoded protein has six transmembrane helices which contain an effector protein binding site. It binds the sterol-sensing domains of sterol regulatory element-binding protein (SREBP) cleavage-activating protein (SCAP) and 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase), and is essential for the sterol-mediated trafficking of these two proteins. It promotes the endoplasmic reticulum retention of SCAP and the ubiquitin-mediated degradation of HMG-CoA reductase. Alternative splicing results in multiple transcript variants.

A study in human menstrual blood-derived stem cells (MenSCs) demonstrated that the INSIG1 (INSIG1), a gene involved in lipid and cholesterol metabolism, was down-regulated with increasing donor age [Chen et al. DOI:PMC4713568]. This differential expression was identified via whole human genome microarray analysis as part of a panel of key genes associated with cellular aging, providing a theoretical base for clinical cellular therapy.
