Protein function: Oxysterol-binding protein that mediates feedback control of cholesterol synthesis by controlling both endoplasmic reticulum to Golgi transport of scap and degradation of hmgcr. Acts as a negative regulator of cholesterol biosynthesis by mediating the retention of the SCAP-SREBP complex in the endoplasmic reticulum, thereby blocking the processing of sterol regulatory element-binding proteins (SREBPs). Binds oxysterol, including 25-hydroxycholesterol, regulating interaction with scap and retention of the SCAP-SREBP complex in the endoplasmic reticulum. In presence of oxysterol, interacts with scap, retaining the SCAP-SREBP complex in the endoplasmic reticulum, thereby preventing scap from escorting SREBPs to the Golgi. Sterol deprivation reduces oxysterol-binding, disrupting the interaction between insig1 and scap, thereby promoting Golgi transport of the SCAP-SREBP complex, followed by processing and nuclear translocation of SREBPs. Also regulates cholesterol synthesis by regulating degradation of hmgcr. [The UniProt Consortium]
