Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 34 kDa (predicted molecular weight: 39 kDa).
  • Application notesIs unsuitable for Flow Cyt,ICC,IHC-P or IP.
  • Target

    • FunctionCasein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. It can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates CTNNB1 at 'Ser-45'. May play a role in segregating chromosomes during mitosis.
    • Sequence similaritiesBelongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. Casein kinase I subfamily.
      Contains 1 protein kinase domain.
    • Cellular localizationCytoplasm. Cytoplasm > cytoskeleton > centrosome. Chromosome > centromere > kinetochore. Nucleus speckle. Localizes to the centrosome in interphase cells, and to kinetochore fibers during mitosis.
