ターゲット情報

  • 機能
    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.
  • 関連疾患
    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.
  • 配列類似性
    Belongs to the bZIP family.
    Contains 1 bZIP domain.
    Contains 1 KID (kinase-inducible) domain.
  • 翻訳後修飾
    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 antibody (ab65741) at 2 µg/ml + J774.1 (J) cell extracts

    Predicted band size : 37 kDa
    Observed band size : 43 kDa (why is the actual band size different from the predicted?)
  • Immunoprecipitation of ab65741 (10µg/mg lysate) with J774.1 cell lysate using:
    protein G beads (lane 1)
    controls using beads alone (lane 2)
    lysate alone (lane 3)
    beads + ab65741 with no lysate (lane 4)
    beads + lysate with no ab65741 (lane 5).
    Western blot analysis by another commercial CREB antibody.
