Application Abreviews Notes
WB Use a concentration of 1.25 µg/ml. Detects a band of approximately 85 kDa (predicted molecular weight: 85 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 4 - 8 µg/ml.


  • Function

    Transient role during the earliest stages of myocardial cell differentiation and/or primitive chamber formation and may also be important for the earliest stages of skeletal muscle growth and/or differentiation. Potential role in G2/M cell cycle regulation. Inhibits CREB activity by phosphorylating and repressing the CREB-specific coactivators, CRTC1-3.
  • Sequence similarities

    Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. AMPK subfamily.
    Contains 1 protein kinase domain.
    Contains 1 UBA domain.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Cytoplasm. Nucleus. Translocates to the cytoplasm on phosphorylation where it binds binding to YWHAZ.
