FIGURE 21-43 SREBP activation. Sterol regulatory element-binding proteins (SREBPs, shown in green) are embedded in the ER when first synthesized, in a complex with the protein SREBP cleavage-activating protein (SCAP, red). (N and C represent the amino and carboxyl termini of the proteins.) When bound to SCAP, SREBPs are inactive. When... 

Includes a timely new discussion on the regulation of cholesterol metabolism at the genetic level, with consideration of sterol regulatory element-binding proteins (SREBPs).

Members of a family of nuclear transcription factors called sterol regulatory element-binding proteins (SREBP) are responsible for the regulation of these cholesterol feedback mechanisms. SREBP are able to activate a number of genes encoding for proteins involved in the homeostasis of cholesterol and other lipids, including the LDL receptor gene itself.
