Research Backgrounds

Function:

Transcriptional activator required for lipid homeostasis. Regulates transcription of the LDL receptor gene as well as the cholesterol and to a lesser degree the fatty acid synthesis pathway (By similarity). Binds the sterol regulatory element 1 (SRE-1) (5'-ATCACCCCAC-3') found in the flanking region of the LDRL and HMG-CoA synthase genes.

PTMs:

At low cholesterol the SCAP/SREBP complex is recruited into COPII vesicles for export from the ER. In the Golgi complex SREBPs are cleaved sequentially by site-1 and site-2 protease. The first cleavage by site-1 protease occurs within the luminal loop, the second cleavage by site-2 protease occurs within the first transmembrane domain and releases the transcription factor from the Golgi membrane. Apoptosis triggers cleavage by the cysteine proteases caspase-3 and caspase-7.

Phosphorylated by AMPK, leading to suppress protein processing and nuclear translocation, and repress target gene expression.

Subcellular Location:

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.

Tissue Specificity:

Ubiquitously expressed in adult and fetal tissues.

Subunit Structure:

Forms a tight complex with SCAP in the ER membrane. Efficient DNA binding of the soluble transcription factor fragment requires dimerization with another bHLH protein. Interacts with LMNA. Component of SCAP/SREBP complex composed of SREBF2, SCAP and RNF139; the complex hampers the interaction between SCAP and SEC24B, thereby reducing SREBF2 proteolytic processing. Interacts (via C-terminal domain) with RNF139.

Family&Domains:

Belongs to the SREBP family.
