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.
Synonyms: Anti-CREB; Anti-cAMP response element-binding protein
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

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-a 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.
