This product was prepared from monospecific antiserum by delipidation and Immunoadsorption against an E.coli lysate immobilized on agarose beads. This antibody may react non-specifically with other proteins. A partial cross-reactivity is observed against CREM-1 protein.
Immunogen
CREB-1 (p43) peptide corresponding to a region near the N-terminus of the Human protein conjugated to Keyhole Limpet Hemocyanin (KLH).
Western Blot: This antibody was assayed against a lysate of 1 x 10^6 Raji B cells byImmunoblot and found to be reactive against CREB-1 (p43), showing a 46 kDa band at adilution of 1/500-1/1,000 followed by reaction with Peroxidase conjugated anti-Rabbit IgG(H&L) [Goat] (Cat#R1364HRP)ELISA: 1/5,000-1/25,000. Immunoprecipitation. Gelshift: This antibody was tested in Gel Supershift Assay and found to be reactive againstCREB-1 (p43) using 0.5-1.0 μL per assay. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Hintergrund
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.Synonyms: CREB-1, Cyclic AMP-responsive element-binding protein 1, cAMP-responsive element-binding protein 1
