靶标

  • 功能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. Transcription activation is enhanced by the TORC coactivators which act independently of Ser-133 phosphorylation. Implicated in synchronization of circadian rhythmicity.
  • 疾病相关Defects in CREB1 may be a cause of angiomatoid fibrous histiocytoma (AFH) [MIM:612160]. A distinct variant of malignant fibrous histiocytoma that typically occurs in children and adolescents and is manifest by nodular subcutaneous growth. Characteristic microscopic features include lobulated sheets of histiocyte-like cells intimately associated with areas of hemorrhage and cystic pseudovascular spaces, as well as a striking cuffing of inflammatory cells, mimicking a lymph node metastasis. Note=A chromosomal aberration involving CREB1 is found in a patient with angiomatoid fibrous histiocytoma. Translocation t(2;22)(q33;q12) with CREB1 generates a EWSR1/CREB1 fusion gene that is most common genetic abnormality in this tumor type.
  • 序列相似性Belongs to the bZIP family.
    Contains 1 bZIP domain.
    Contains 1 KID (kinase-inducible) domain.
  • 翻译后修饰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 binding (By similarity). Phosphorylated upon DNA damage, probably by ATM or ATR.
    Sumoylated by SUMO1. Sumoylation on Lys-304, but not on Lys-285, is required for nuclear localization of this protein. Sumoylation is enhanced under hypoxia, promoting nuclear localization and stabilization.

Anti-CREB (phospho S133) antibody [E113] 图像

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human thyroid carcinoma tissue labelling CREB with purified ab32096 at 1/100. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. ab97051, a goat anti-rabbit IgG H&L (HRP) was used as the secondary antibody (1/500). Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of rat hippocampus tissue labelling CREB with unpurified ab32096 at 1/100 dilution. Sections were subjected to antigen retrieval by autoclave prior to blocking with 8% milk for 30 minutes at 37°C. The primary antibody was diluted 1/100 with DAKO antibody diluent and incubated with the sample for 18 hours at 4°C. An LSAB-labeled Streptavidin-Biotin conjugated Goat polyclonal antibody was used undiluted as the secondary antibody.

    SK-N-SH cells were incubated at 37&degC for 30 minutes with vehicle control (0 &microM) and different concentrations of (S)-3,5-DHPG (ab120007). Increased expression of CREB (phospho S133) in SK-N-SH cells correlates with an increase in (S)-3,5-DHPGconcentration, as described in literature.

    Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 20&microg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 3% milk before being incubated with unpurified ab32096 at 1/500 dilution and ab32515 at 1 &microg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 dilution and visualised using ECL development solution.
