      Background InformationCyclic AMP-responsive element-binding protein 1 (UniProt: P16220; also known as CREB-1, cAMP-responsive element-binding protein 1) is encoded by the CREB1 gene (Gene ID: 1385) in human. CREB is a phosphorylation-dependent transcription factor that stimulates transcription upon binding to the DNA cAMP response element (CRE; TGACGTCA) as a dimer. It is essential for the activation of a number of immediate early genes. It also plays a key role in promoting neuronal survival, differentiation, proliferation, and neurite outgrowth. Transcription activation is reported to be enhanced by the TORC coactivators. CREB has four main functional domains: a C-terminal basic/leucine zipper domain (bZIP; aa 269-327), the Kinase Inducible Domain at the N-terminal (KID; aa 87-146), and two glutamine-rich domains (Q1, and Q2). The Q1 and Q2 domains provide transactivation function in the absence of cAMP signaling and synergize with KID and bZIP to confer full activity to CREB in response to cAMP. CREB is phosphorylated on serine 133 by protein kinase A, which promotes the recruitment of the co-activator CREB-binding protein(CBP) and p300 that increases the transcription of CREB-dependent genes. CREB is also phosphorylated on serine 133 by mitogen- and stress-activated kinase 1/2 (MASK 1/2) in cells in response to the activation of MAPK signaling. Phosphorylation of CREB is sufficient to induce cellular gene expression in response to cAMP, however, additional promoter-bound factors are required for target gene activation by CREB in response to mitogen or stress signals, indicating the presence of components in the CREB pathway that discriminate between different types of inputs.

      Biological Information
      ImmunogenKLH-conjugated, synthetic peptide (REILSRRP(pS)YR) corresponding to amino acids 125-135 of human CREB. The immunizing sequence is identical in human and mouse. Clone 10E9.
      Cloneclone 10E9
      SpecificityRecognizes phosphorylated CREB at Mr 46 kDa. May also recognize p30 and p38 proteins, which likely correspond to phosphorylated CREM and ATF-1 respectively, since the two proteins share significant homology with the phosphorylated CREB immunizing peptide

      Entrez Gene Number
      Entrez Gene SummaryThis 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, an octameric palindrome. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Alternate splicing of this gene results in two transcript variants encoding different isoforms.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P16220 # This protein binds the cAMP response element (CRE), a sequence present in many viral and cellular promoters. CREB stimulates transcription on binding to the CRE.
      SIZE: 341 amino acids; 36688 Da
      SUBUNIT: Binds DNA as a dimer. Interacts PPRC1 and with HTLV-1 Tax-1.
      PTM: Stimulated by phosphorylation. Phosphorylation of both Ser- 133 and Ser-142 in the SCN regulates the activity of CREB and participates in circadian rhythm generation. Phosphorylation of Ser-133 allows CREBBP and EP300 binding (By similarity). Phosphorylated upon DNA damage, probably by ATM or ATR.
      SIMILARITY: SwissProt: P16220 ## Belongs to the bZIP family. & Contains 1 bZIP domain. & Contains 1 KID (kinase-inducible) domain.
