Supplementary information

SCAP also known as SREBP cleavage-activating protein is an important player in lipid homeostasis. SCAP has a molecular mass of approximately 150 kDa. It locates in the endoplasmic reticulum and Golgi apparatus within cells. The protein facilitates the movement of sterol regulatory element-binding proteins (SREBPs) from the endoplasmic reticulum to the Golgi. This action activates SREBPs by enabling their cleavage which is necessary for cholesterol and lipid synthesis regulation.
Biological function summary

SCAP acts as a cholesterol sensor when paired with SREBPs in a complex. The SCAP-SREBP complex remains inactive within the endoplasmic reticulum at high cholesterol concentrations. When cholesterol levels decrease SCAP aids in the transport of SREBPs to the Golgi apparatus. This transport triggers proteolytic activation of SREBPs which then migrate to the nucleus to promote gene expression for lipid metabolism.

Pathways

SCAP is instrumental in the cholesterol biosynthesis and lipid metabolic pathways. The protein interacts closely with SREBPs in these pathways to regulate lipid balance within cells. In particular SCAP's action is linked with the insulin signaling pathway aiding in the coordination of growth factor-mediated lipid synthesis. This highlights its importance in the control of lipid-related gene transcription together with proteins like Insig which anchor the SCAP-SREBP complex under high cholesterol levels.

SCAP plays a role in metabolic syndrome and cardiovascular diseases. Dysregulation of SCAP can lead to abnormal cholesterol levels contributing to atherosclerosis and other lipid disorders. The function of SCAP connects to proteins like HMG-CoA reductase in these conditions as it co-regulates the synthesis of cholesterol. Understanding SCAP's role in these diseases may open new therapeutic strategies for managing cholesterol-related disorders.

Target data

Escort protein required for cholesterol as well as lipid homeostasis (By similarity). Regulates export of the SCAP-SREBP complex from the endoplasmic reticulum to the Golgi upon low cholesterol, thereby regulating the processing of sterol regulatory element-binding proteins (SREBPs) SREBF1/SREBP1 and SREBF2/SREBP2 (PubMed : 26311497). At high sterol concentrations, formation of a ternary complex with INSIG (INSIG1 or INSIG2) leads to mask the ER export signal in SCAP, promoting retention of the complex in the endoplasmic reticulum (By similarity). Low sterol concentrations trigger release of INSIG, a conformational change in the SSD domain of SCAP, unmasking of the ER export signal, promoting recruitment into COPII-coated vesicles and transport of the SCAP-SREBP to the Golgi : in the Golgi, SREBPs are then processed, releasing the transcription factor fragment of SREBPs from the membrane, its import into the nucleus and up-regulation of LDLR, INSIG1 and the mevalonate pathway (PubMed : 26311497). Binds cholesterol via its SSD domain (By similarity).
