Application Details

Application Notes:

Immunohistochemistry Dilution: 20 μg/mL

Application Note: Anti-CREB pS133 antibody reacts with phosphorylated human CREB at pS133 and shows minimal reactivity by western blot with non-phosphorylated CREB and minimal reactivity (1 % ) by ELISA against the non-phosphorylated form of the immunizing peptide.  This antibody was assayed against a variety of tissues including fibroblasts and B-cell lysates.  Bands of 46 and 43 kDa corresponding to phosphorylated CREB are observed in western blots.  Anti-CREB pS133 is suitable for the detection by immunoblot of phosphorylated human, mouse and rat CREB.  No cross-reactivity occurs with non-phosphorylated CREB.  For immunohistochemistry, formalin fixed, paraffin embedded human tissue shows moderate to strong nuclear staining in a variety of cells with minimal background staining.  Although not tested this antibody is likely functional by FACS and immunoprecipitation.

Target Details for CREB1

Target: CREB1 (cAMP Responsive Element Binding Protein 1 (CREB1))

Alternative Name: CREB1 (CREB1 Products)

Background: Background: The CREB (Cyclic AMP-response-element-binding-protein 1) gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds as a homodimer to the cAMP-responsive element (CRE element TGANNTCA), an octameric palindrome. Phosphorylation by cAMP-dependent protein kinase (PKA) at serine-119 is required for interaction with DNA and phosphorylation at serine-133 allows CREB to interact with CBP (CREB binding protein) leading to interaction with RNA polymerase II.  Alternate splicing of this gene results in two transcript variants encoding different isoforms.
