Product Description
CREB (phospho Ser133) Antibody | 50-221 | ProSci
Host: Rabbit
Reactivity: Human, Mouse, Rat, Dog, Bovine, Sheep, Zebrafish
Homology: N/A
Immunogen: Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser133 of rat CREB.
Research Area: Phospho-Specific
Tested Application: WB
Application: The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will also react with bovine, canine, chicken, human, mouse, non-human primate, rat, sheep, Xenopus and zebra fish based on the fact that these species have 100% homology with the amino acid sequence used as antigen.

BACKGROUND: It is well known that the control of gene expression involves activation of protein kinase cascades that regulate transcription factors within the nucleus (Karin and Hunter, 1995) . The cyclic AMP response element binding protein (CREB) is one of the best characterized stimulus-induced transcription factors (Montminy, 1997) . This transcription factor is a component of intracellular signaling events that regulate a wide range of biological functions, from spermatogenesis to circadian rhythms and memory (Shaywitz and Greenberg, 1999; Silva et al., 1998) . A variety of protein kinases including protein kinase A (PKA) , mitogenactivated protein kinases (MAPKs) , and Ca2+/calmodulin-dependent protein kinases (CaMKs) phosphorylate CREB at serine 133 (Ser133) , and phosphorylation of Ser133 are required for CREB-mediated transcription (Johannessen et al., 2004; Kornhauser et al., 2002) .
