Anti-CREB1 antibody produced in rabbit
SIGMA/HPA019150 - Prestige Antibodies® Powered by Atlas Antibodies, affinity isolated antibody, buffered aqueous glycerol solution
Synonym: Anti-CREB; Anti-cAMP response element-binding protein
Product Type: Chemical
ChIP-Exo-Seq composite graph for Anti-CREB1 (HPA019150, Lot 000012256) tested in K562 cells. Strand-specific reads (blue: forward, red: reverse) and IgG controls (black: forward, grey: reverse) are plotted against the distance from a composite set of reference binding sites. The antibody exhibits robust target enrichment compared to a non-specific IgG control and precisely reveals its structural organization around the binding site. Data generated by Prof. B. F. Pugh´s Lab at Cornell University. *Please note not all antibody batches are validated for use in ChIP applications.
Immunohistochemistry Immunohistochemical staining of human small intestine shows strong nuclear positivity in glandular cells.
Immunofluorescence Immunofluorescent staining of human cell line U-2 OS shows localization to nucleoplasm.

| Application: | All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information. |
| Biochem/physiol Actions: | CREB1 (cyclic AMP-responsive element-binding protein 1) is a cAMP (cyclic adenosine monophosphate) responsive transcription factor which is important for neuronal signal transduction. It is involved in cell division and apoptosis. CREB1 is phosphorylated by cAMP-dependent protein kinase A, Ca2+-calmodulin, AKT (RAC-α serine/threonine-protein kinase), p38 MAPK (mitogen-activated protein kinase 1), JNK (c-Jun N-terminal kinase), and other kinases. Phosphorylation increases the transcriptional activity of CREB1 and its association with the co-activator, CREB-binding protein (CBP). Polymorphism in CREB1 is associated with major depressive disorder. It also participates in Kaposi′s Sarcoma-associated herpesvirus lytic replication during primary infection. CREB1 is also linked with schizophrenia. |
| Features and Benefits: | Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section. Every Prestige Antibody is tested in the following ways: • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. • Protein array of 364 human recombinant protein fragments. |
| General description: | The gene CREB1 (cyclic AMP-responsive element-binding protein 1) is mapped to human chromosome 2q34. It is a member of the leucine zipper family of DNA-binding proteins. CREB1 is widely expressed. |
| Immunogen: | cAMP response element-binding protein recombinant protein epitope signature tag (PrEST) |
