Anti-SREBP1 antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a N-terminal portion of human SREBP1 conjugated to Keyhole Limpet Hemocyanin (KLH). if (typeof window.$mangular === undefined || !window.$mangular) { window.$mangular = {}; } $mangular.antigenJson = \[{targetFamily:SREBP1,uniProtId:P36956-1,ncbiNodeId:9606,antigenRange:1,antigenLength:1147,antigenImageFileName:600-401-MN1_SREBP1_P36956-1_Rabbit.svg,antigenImageFileNamePDP:600-401-MN1_SREBP1_P36956-1_Rabbit_PDP.jpeg,sortOrder:1}\]; $mangular.isB2BCMGT = false; $mangular.isEpitopesModalImageMultiSizeEnabled = true;

Product Specific Information

Store vial at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.

This affinity purified antibody is directed against human SREBP1. A BLAST analysis was used to suggest cross-reactivity with the antigen based on 100% homology with the immunizing sequence with human, 92.9% with swine, and 85.7% with rat.

Target Information

Sterol regulatory element-binding proteins (SREBPs) are transcription factors that are members of the basic helix-loop-helix leucine zipper family of DNA binding proteins. Three isoforms have been identified in mammalian tissues that vary in structure, regulation, and function. SREBP-1a and SREBP-1c (originally cloned as ADD1) are protein products of alternative promoter usage of the SREBP-1 gene. The third isoform is transcribed from a different gene, SREBP-2. SREBPs are present as 120 kDa inactive precursors in the endoplasmic reticulum (ER) membrane. Upon activation, the SREBP protein is translocated to the Golgi and proteolytic cleavage occurs resulting in a mature transcriptionally active 60-78 kDa fragment. In liver and adipose tissues, SREBPs have a significant influence on lipid and cholesterol accumulation by inducing the transcription of genes involved in these processes. While SREBP-1 is thought to be more important in regulating the expression of genes involved in triglyceride synthesis and accumulation, SREBP-2 has been more closely linked to those involved in cholesterol synthesis and accumulation.
