FunctionEscort protein required for cholesterol as well as lipid homeostasis. Regulates export of the SCAP/SREBF complex from the ER upon low cholesterol. Formation of a ternary complex with INSIG at high sterol concentrations leads to masking of an ER-export signal in SCAP and retention of the complex in the ER. Low sterol concentrations trigger release of INSIG, a conformational change in the SSC domain of SCAP, unmasking of the ER export signal, recruitment into COPII-coated vesicles, transport to the Golgi complex, proteolytic cleavage of SREBF in the Golgi, release of the transcription factor fragment of SREBF from the membrane, its import into the nucleus and up-regulation of LDLR, INSIG1 and the mevalonate pathway.
Sequence similaritiesBelongs to the WD repeat SCAP family.
Contains 1 SSD (sterol-sensing) domain.
Contains 7 WD repeats.
DomainCholesterol bound to SSC domain of SCAP or oxysterol bound to INSIG1/2 leads to masking of an ER export signal on SCAP possibly by moving the signal further away from the ER membrane.
Cellular localizationEndoplasmic reticulum membrane. Golgi apparatus membrane. Cytoplasmic vesicle > COPII-coated vesicle membrane. Moves from the endoplasmic reticulum to the Golgi in the absence of sterols.
