Homo sapiens cAMP responsive element binding protein 1 (CREB1), transcript variant B
A synthetic phospho-peptide corresponding to residues surrounding Ser133 of human CREB was used as immunogen. The antibody only detects CREB phosphorylated on Serine 133. Predicted to cross-react with bovine, chicken, and zebra fish, based on sequence hom

CREB is a transcription factor protein that binds the cAMP response element (CRE), thereby stimulating transcription of this sequence. CREB plays a role in propagating numerous extracellular signals to the nuclues (1-3). CREB is activated by phosphorylation at the Ser133 position by various signaling pathways, and some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV and MAPKAPK-2 (1-3).
