83. Sterol regulatory element-binding protein (SREBP) controls the gene expression of cholesterol biosynthesis. What happens when there is the presence of a high cellular concentration of cholesterol? (A) It increases the proteolytic cleavage and releases SREBP into the nucleus. (B) SREBP is hold in the Golgi apparatus in a complex with SREBP-cleavage-activating protein (SCAP) to produce a regulatory domain fragment. (C) It activates SREBP by inducing the conformational change for cholesterol biosynthesis. (D) It stabilizes the SCAP-SREBP complex by the anchoring of insulin-induced gene protein (Insig). (E) SREBP acts as a corepressor of RXR-LXR dimer to terminate the gene expression of cholesterol biosynthesis.
