CC   -!- FUNCTION: [Sterol regulatory element-binding protein 1]: Precursor of
CC       the transcription factor form (Processed sterol regulatory element-
CC       binding protein 1), which is embedded in the endoplasmic reticulum
CC       membrane (By similarity). Low sterol concentrations promote processing
CC       of this form, releasing the transcription factor form that translocates
CC       into the nucleus and activates transcription of genes involved in
CC       cholesterol biosynthesis and lipid homeostasis (By similarity).
CC       {ECO:0000250|UniProtKB:P36956, ECO:0000250|UniProtKB:Q9WTN3}.
CC   -!- FUNCTION: [Processed sterol regulatory element-binding protein 1]: Key
CC       transcription factor that regulates expression of genes involved in
CC       cholesterol biosynthesis and lipid homeostasis (By similarity). Binds
CC       to the sterol regulatory element 1 (SRE-1) (5'-ATCACCCCAC-3')
CC       (PubMed:7739539). Has dual sequence specificity binding to both an E-
CC       box motif (5'-ATCACGTGA-3') and to SRE-1 (5'-ATCACCCCAC-3') (By
CC       similarity). Regulates the promoters of genes involved in cholesterol
CC       biosynthesis and the LDL receptor (LDLR) pathway of sterol regulation
CC       (By similarity). {ECO:0000250|UniProtKB:P36956,
CC       ECO:0000269|PubMed:7739539}.
CC   -!- FUNCTION: [Isoform SREBP-1A]: Isoform expressed only in select tissues,
CC       which has higher transcriptional activity compared to SREBP-1C (By
CC       similarity). Able to stimulate both lipogenic and cholesterogenic gene
CC       expression (By similarity). Has a role in the nutritional regulation of
CC       fatty acids and triglycerides in lipogenic organs such as the liver.
CC       Required for innate immune response in macrophages by regulating lipid
CC       metabolism (By similarity). {ECO:0000250|UniProtKB:P36956,
CC       ECO:0000250|UniProtKB:Q9WTN3}.
CC   -!- FUNCTION: [Isoform SREBP-1C]: Predominant isoform expressed in most
CC       tissues, which has weaker transcriptional activity compared to isoform
CC       SREBP-1A (By similarity). Primarily controls expression of lipogenic
CC       gene (By similarity). Strongly activates global lipid synthesis in
CC       rapidly growing cells (By similarity). {ECO:0000250|UniProtKB:P36956,
CC       ECO:0000250|UniProtKB:Q9WTN3}.
CC   -!- SUBUNIT: [Sterol regulatory element-binding protein 1]: Forms a tight
CC       complex with SCAP, the SCAP-SREBP complex, in the endoplasmic reticulum
CC       membrane. {ECO:0000250|UniProtKB:P36956}.
CC   -!- SUBUNIT: [Processed sterol regulatory element-binding protein 1]:
CC       Efficient DNA binding of the soluble transcription factor fragment
CC       requires dimerization with another bHLH protein (By similarity).
CC       Interacts with CEBPA, the interaction produces a transcriptional
CC       synergy. Interacts with LMNA (By similarity).
CC       {ECO:0000250|UniProtKB:P36956, ECO:0000250|UniProtKB:Q9WTN3}.
CC   -!- SUBCELLULAR LOCATION: [Sterol regulatory element-binding protein 1]:
CC       Endoplasmic reticulum membrane {ECO:0000250|UniProtKB:P36956}; Multi-
CC       pass membrane protein {ECO:0000255}. Golgi apparatus membrane
CC       {ECO:0000250|UniProtKB:Q9WTN3}; Multi-pass membrane protein
CC       {ECO:0000255}. Cytoplasmic vesicle, COPII-coated vesicle membrane
CC       {ECO:0000250|UniProtKB:Q9WTN3}; Multi-pass membrane protein
CC       {ECO:0000255}. Note=At high sterol concentrations, the SCAP-SREBP is
CC       retained in the endoplasmic reticulum. Low sterol concentrations
CC       promote recruitment into COPII-coated vesicles and transport of the
CC       SCAP-SREBP to the Golgi, where it is processed.
CC       {ECO:0000250|UniProtKB:Q9WTN3}.
CC   -!- SUBCELLULAR LOCATION: [Processed sterol regulatory element-binding
CC       protein 1]: Nucleus {ECO:0000250|UniProtKB:P36956}.
CC   -!- ALTERNATIVE PRODUCTS:

CC       Name=SREBP-1C; Synonyms=ADD1;
CC         IsoId=P56720-1; Sequence=VSP_030860;
CC   -!- TISSUE SPECIFICITY: Expressed predominantly in brown adipose tissue.
CC       {ECO:0000269|PubMed:8336713}.
CC   -!- DOMAIN: The 9aaTAD motif is a transactivation domain present in a large
CC       number of yeast and animal transcription factors.
CC       {ECO:0000250|UniProtKB:P36956}.
CC   -!- PTM: [Sterol regulatory element-binding protein 1]: Processed in the
CC       Golgi apparatus, releasing the protein from the membrane. At low
CC       cholesterol the SCAP-SREBP complex is recruited into COPII vesicles for
CC       export from the endoplasmic reticulum. In the Golgi, complex SREBPs are
CC       cleaved sequentially by site-1 (MBTPS1, S1P) and site-2 (MBTPS2, S2P)
CC       proteases. The first cleavage by site-1 protease occurs within the
CC       luminal loop, the second cleavage by site-2 protease occurs within the
CC       first transmembrane domain, releasing the transcription factor from the
CC       Golgi membrane. {ECO:0000250|UniProtKB:P36956}.
CC   -!- PTM: Phosphorylated by AMPK, leading to suppress protein processing and
CC       nuclear translocation, and repress target gene expression.
CC       Phosphorylation at Ser-395 by SIK1 represses activity possibly by
CC       inhibiting DNA-binding. {ECO:0000250|UniProtKB:Q9WTN3}.
CC   -!- PTM: [Processed sterol regulatory element-binding protein 1]:
CC       Ubiquitinated; the nuclear form has a rapid turnover and is rapidly
CC       ubiquitinated and degraded by the proteasome in the nucleus.
CC       {ECO:0000250|UniProtKB:P36956}.
CC   -!- SIMILARITY: Belongs to the SREBP family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=L16995; Type=Frameshift; Evidence={ECO:0000305};
