When cellμlar sterol stores are depleted, the element is activated, the gene is transcribed and the cellμlar uptake of LDL increases. SREBP-1 (also designated ADD1, for adipocyte determination and differentiation factor) is synthesized as a precursor that is attached to the nuclear envelope and endoplasmic reticμlum. In sterol-depleted cells, the membrane-bound precursor is cleaved to generate a soluble NH2-terminal fragment that translocates to the nucleus to activate transcription. Sterols inhibit the cleavage of SREBP-1.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Rat, Mouse\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Sterol regμlatory element-binding protein 1, SREBP-1, Class D basic helix-loop-helix protein 1, bHLHd1, Sterol regμlatory element-binding transcription factor 1, Processed sterol regμlatory element-binding protein 1, SREBF1, BHLHD1, SREBP1\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Phosphorylation\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Synthetic phosphopeptide derived from human SREBP-1 around the phosphorylation site of Serine 439\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB: 1:500~1:1000\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: SREBP-1 (phospho-S439) polyclonal antibody detects endogenous levels of SREBP-1 protein only when phosphorylated at Ser439.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 121 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
