Clonality	Polyclonal
Immunogen	The antiserum was produced against synthesized phosphopeptide derived from human CREB around the phosphorylation site of Serine 129 (I-L-SP-R-R).
Specificity	This antibody detects endogenous levels of CREB only when phosphorylated at Serine 129.
Formulation	PBS (without Mg2+ and Ca2+), pH 7.4 containing 150 mM NaCl, 0.02% Sodium Azide and 50% Glycerol. State: Aff - Purified State: Liquid purified IgG fraction.
Concentration	lot specific
Purification	Afinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Conjugation	Unconjugated
Storage Condition	Store the antibody (in aliquots) at -20°C. Avoid repeated freezing and thawing.
Gene Name	cAMP responsive element binding protein 1
Database Link	Entrez Gene 1385 Human UniProt ID P16220
Background	Cyclic AMP Response Element Binding protein (CREB) is a 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 occurs via p44 / 42 MAP kinase and p90RSK and also via p38 MAP kinase and MSK 1. 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 appears to play an important role in learning and memory. CREB knock out mice show diminished learning ability. Alternate splicing of this gene results in two transcript variants encoding different isoforms.
Synonyms	CREB-1
