製品説明
*The optimal dilutions should be determined by the end user. For optimal experimental results, antibody reuse is not recommended.
*Tips:
WB: For western blot detection of denatured protein samples. IHC: For immunohistochemical detection of paraffin sections (IHC-p) or frozen sections (IHC-f) of tissue samples. IF/ICC: For immunofluorescence detection of cell samples. ELISA(peptide): For ELISA detection of antigenic peptide.

研究背景
Escort 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 (By similarity).
Ubiquitinated at Lys-454 and Lys-466. RNF145 triggers ubiquitination of SCAP, likely inhibiting SCAP:SREBPF2 complex transport to the Golgi apparatus and the subsequent processing/maturation of SREBPF2.
Endoplasmic reticulum membrane>Multi-pass membrane protein. Golgi apparatus membrane>Multi-pass membrane protein. Cytoplasmic vesicle>COPII-coated vesicle membrane>Multi-pass membrane protein.
Note: Moves from the endoplasmic reticulum to the Golgi in the absence of sterols.
Cholesterol 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.
Belongs to the WD repeat SCAP family.
