SREBP-1 (Phospho-Ser439) Colorimetric Cell-Based ELISA Kit
The SREBP-1 (Phospho-Ser439) Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor SREBP-1 (Phospho-Ser439) protein expression profile in cells. The kit can be used for measuring the relative amounts of SREBP-1 (Phospho-Ser439) in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on SREBP-1 (Phospho-Ser439) .

Reactivity
Human, Rat
Tissue Specificity
Expressed in a wide variety of tissues, most abundant in liver and adrenal gland. In fetal tissues lung and liver shows highest expression. Isoform SREBP-1C predominates in liver, adrenal gland and ovary, whereas isoform SREBP-1A predominates in hepatoma cell lines. Isoform SREBP-1A and isoform SREBP-1C are found in kidney, brain, white fat, and muscle.
Applications
ELISA
Detection Range
> 5000 cells/well
Function
Transcriptional activator required for lipid homeostasis. Regulates transcription of the LDL receptor gene as well as the fatty acid and to a lesser degree the cholesterol synthesis pathway (By similarity) . 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') .
