The antibody detects endogenous level of SREBP-1 only when phosphorylated at serine 439.
纯化方法
Antibodies were purified by affinity-chromatography using epitope-specific peptide.
免疫原
SREBP-1 (phospho Ser439) antibody was raised against a peptide sequence around phosphorylation site of serine439 (Q-S-S (p)-P-L) derived from Human SREBP-1 .
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').
