Verification Image

Western blot analysis of extracts from Hela(lane 2(20μg) , HepG2(lane 3(20ug) and HEK293(lane 4(40ug) using SREBP1 Antibody (HY-P80900) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

Background

Function：Precursor of the transcription factor form (Processed sterol regulatory element-binding protein 1), which is embedded in the endoplasmic reticulum membrane (PubMed:32322062). Low sterol concentrations promote processing of this form, releasing the transcription factor form that translocates into the nucleus and activates transcription of genes involved in cholesterol biosynthesis and lipid homeostasis (By similarity); Key transcription factor that regulates expression of genes involved in cholesterol biosynthesis and lipid homeostasis (PubMed:12177166, PubMed:32322062, PubMed:8402897). Binds to the sterol regulatory element 1 (SRE-1) (5'-ATCACCCCAC-3'). Has dual sequence specificity binding to both an E-box motif (5'-ATCACGTGA-3') and to SRE-1 (5'-ATCACCCCAC-3') (PubMed:12177166, PubMed:8402897). Regulates the promoters of genes involved in cholesterol biosynthesis and the LDL receptor (LDLR) pathway of sterol regulation (PubMed:12177166, PubMed:32322062, PubMed:8402897); Isoform expressed only in select tissues, which has higher transcriptional activity compared to SREBP-1C (By similarity). Able to stimulate both lipogenic and cholesterogenic gene expression (PubMed:12177166, PubMed:32497488). Has a role in the nutritional regulation of fatty acids and triglycerides in lipogenic organs such as the liver (By similarity). Required for innate immune response in macrophages by regulating lipid metabolism (By similarity); Predominant isoform expressed in most tissues, which has weaker transcriptional activity compared to isoform SREBP-1A (By similarity). Primarily controls expression of lipogenic gene (PubMed:12177166). Strongly activates global lipid synthesis in rapidly growing cells (By similarity); The absence of Golgi proteolytic processing requirement makes this isoform constitutively active in transactivation of lipogenic gene promoters; The absence of Golgi proteolytic processing requirement makes this isoform constitutively active in transactivation of lipogenic gene promoters

Expression：
Tissue_specificity:This gene is expressed in various tissues, with the highest abundance in the liver and adrenal glands (PubMed:8402897) . In fetal tissues, the highest expression levels are found in the lungs and liver (PubMed:8402897) ; it is dominant in hepatocellular carcinoma cell lines (PubMed:8402897) . This gene is also expressed in the kidneys, brain, white adipose tissue, and muscle (PubMed:8402897) ; it is primarily expressed in the liver and adipose tissue (PubMed:8402897) . This gene is also expressed in the kidneys, brain, white adipose tissue, and muscle (PubMed:8402897) .

Isoforms & Post-Translational Modification：P36956 has 6 isomers: P36956-1: 121675 Da (predicted); P36956-2: 113562 Da (predicted); P36956-3: 111102 Da (predicted); P36956-4: 124635 Da (predicted); P36956-5: 48276 Da (predicted); P36956-6: 45816 Da (predicted).
Processed in the Golgi apparatus, releasing the protein from the membrane (PubMed:32322062, PubMed:8626610). At low cholesterol the SCAP-SREBP complex is recruited into COPII vesicles for export from the endoplasmic reticulum (PubMed:32322062, PubMed:8626610). In the Golgi, complex SREBPs are cleaved sequentially by site-1 (MBTPS1, S1P) and site-2 (MBTPS2, S2P) protease (PubMed:32322062, PubMed:8626610). 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, releasing the transcription factor from the Golgi membrane (PubMed:32322062);Phosphorylated by AMPK, leading to suppress protein processing and nuclear translocation, and repress target gene expression (By similarity). Phosphorylation at Ser-402 by SIK1 represses activity possibly by inhibiting DNA-binding (By similarity);SCAP-free SREBF1 is ubiquitinated by the BCR(ARMC5) complex, leading to its degradation;Ubiquitinated; the nuclear form has a rapid turnover and is rapidly ubiquitinated and degraded by the proteasome in the nucleus

Subunit：Forms a tight complex with SCAP, the SCAP-SREBP complex, in the endoplasmic reticulum membrane and the Golgi apparatus (PubMed:32322062). Interacts with PAQR3; the interaction anchors the SCAP-SREBP complex to the Golgi apparatus in low cholesterol conditions (PubMed:26311497)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
