      Background InformationCREB is a beta ZIP transcription factor that activates target genes through cAMP response elements. CREB is able to mediate signals from numerous physiological stimuli, resulting in regulation of a broad array of cellular responses. While CREB is expressed in numerous tissues, it plays a large regulatory role in the nervous system. CREB is believed to play a key role in promoting neuronal survival, precursor proliferation, neurite outgrowth and neuronal differentiation in certain neuronal populations. Additionally, CREB signaling is involved in learning and memory in several organisms. CREB is able to selectively activate numerous downstream genes through interactions with different dimerization partners. CREB is activated by phosphorylation at Ser133 by various signaling pathways including Erk, Ca2+ and stress signaling. Some of the kinases involved in phosphorylating CREB at Ser133 are p90RSK, MSK, CaMKIV and MAPKAPK-2.

      ApplicationAnti-phospho-CREB (Ser133) Antibody, clone 10E9 is a Mouse Monoclonal Antibody for detection of phospho-CREB (Ser133) also known as active transcription factor CREB & has been validated in WB, ELISA.
      Key Applications
      • Western Blotting
      • ELISA
      Application NotesELISA: Recommended at 0.05 μg/mL by an independent laboratory.
      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.
