Phospho-CREB(S133) Antibody

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

  • WB - Phospho-CREB(S133) Antibody AP3077a
    Western blot analysis of anti-Phospho-CREB-pS133 Pab (Cat. #AP3077a) in CEM cell line tissue lysate (35ug/lane).Phospho-CREB-pS133(arrow) was detected using the purified Pab.
  • IHC-P - Phospho-CREB(S133) Antibody AP3077a
    Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by AEC staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.

Protein Information
Name CREB1
Function Phosphorylation-dependent transcription factor that stimulates transcription upon binding to the DNA cAMP response element (CRE), a sequence present in many viral and cellular promoters. Transcription activation is enhanced by the TORC coactivators which act independently of Ser-133 phosphorylation. Involved in different cellular processes including the synchronization of circadian rhythmicity and the differentiation of adipose cells.
Cellular Location Nucleus {ECO:0000255|PROSITE- ProRule:PRU00312, ECO:0000255|PROSITE-ProRule:PRU00978, ECO:0000269|PubMed:12552083}

CREB is 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), a sequence present in many viral and cellular promoters. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway.
