Product Specific Information

PA1-850 detects both the phosphorylated and non-phosphorylated forms of cyclic-AMP response element binding protein (CREB) from rat, mouse, and human samples.

PA1-850 has been successfully used in ChIP, Western blot, ICC/IF and IHC-P procedures. By Western blot, this antibody detects an ~43 kDa protein representing CREB from GH4 cell extract.

The PA1-850 immunogen is a synthetic peptide corresponding to residues K(123) R R E I L S R R P S Y R K(136) of human CREB. This sequence is completely conserved between human, bovine, canine, mouse, pig, sheep, and rat CREB protein. The PA1-850 immunizing peptide (Cat. # PEP-142) is available for use in neutralization and control experiments.

Target Information

CREB (Cyclic AMP response element binding protein) is a 43 kDa basic/leucine zipper transcription factor that binds the cyclic AMP response element (CRE) and activates transcription in response to a variety of extracellular signals including neurotransmitters, hormones, membrane depolarization, and growth and neurotrophic factors. Activation of CREB is dependent upon the phosphorylation of serine 133. Phosphorylation of CREB occurs via p44/42 MAP kinase and p90RSK, and via p38 MAP kinase and MSK1. Although CREB will bind DNA independent of its phosphorylation state, only the phosphorylated form is competent as a transcription factor. CREB binding protein (CBP), a transcriptional coactivator that directly interacts with CREB, binds to CREB in the region of serine 133. CREB is involved in different cellular processes including the synchronization of circadian rhythmicity, differentiation of adipose cells, and learning and memory. In humans, the gene is located on the q arm of chromosome 2. Diseases associated with CREB dysfunction include Alzheimer`s Disease, histiocytoma and soft tissue melanoma.
