The PhosphoPlus CREB (Ser133) Antibody Kit provides reagents and protocols for the rapid analysis of the phosphorylation status of CREB at Ser133.
Specificity / Sensitivity
Phospho-CREB (Ser133) (87G3) Rabbit mAb detects endogenous levels of CREB only when phosphorylated at Ser133. This antibody also detects the phosphorylated form of CREB-related protein ATF-1. CREB (48H2) Rabbit mAb detects endogenous levels of total CREB protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser133 of human CREB (Phospho-CREB (Ser133) (87G3) Rabbit mAb), or with a synthetic peptide corresponding to residues near the carboxy-terminus of human CREB (CREB (48H2) Rabbit mAb).
CREB is a bZIP transcription factor that activates target genes through cAMP response elements. CREB is able to mediate signals from numerous physiological stimuli, resulting in regulation of a broad array of cellular responses. While CREB is expressed in numerous tissues, it plays a large regulatory role in the nervous system. CREB is believed to play a key role in promoting neuronal survival, precursor proliferation, neurite outgrowth, and neuronal differentiation in certain neuronal populations (1-3). Additionally, CREB signaling is involved in learning and memory in several organisms (4-6). CREB is able to selectively activate numerous downstream genes through interactions with different dimerization partners. CREB is activated by phosphorylation at Ser133 by various signaling pathways including Erk, Ca2+, and stress signaling. Some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV, and MAPKAPK-2 (7-9).
