  • Function

    Casein 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. Central component of the circadian clock. May act as a negative regulator of circadian rhythmicity by phosphorylating PER1 and PER2. Retains PER1 in the cytoplasm.
  • Tissue specificity

    Expressed in all tissues examined, including brain, heart, lung, liver, pancreas, kidney, placenta and skeletal muscle. In blood, highly expressed in hemopoietic cells and mature granulocytes. Also found in monocytes and lymphocytes.
  • Involvement in disease

    Defects in CSNK1D are a cause of familial advanced sleep-phase syndrome (FASPS) [MIM:604348]. FASPS is characterized by very early sleep onset and offset. Individuals are 'morning larks' with a 4 hours advance of the sleep, temperature and melatonin rhythms.
  • Sequence similarities

    Belongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. Casein kinase I subfamily.
    Contains 1 protein kinase domain.
  • Post-translational

    Autophosphorylated on serine and threonine residues.
  • Cellular localization

    Cytoplasm. Nucleus.

  • Anti-Casein Kinase 1 delta/CSNK1D antibody (ab48031) at 0.3 µg/ml + HEK 293 cell lysate in RIPA buffer at 35 µg

    Predicted band size: 47 kDa
    Observed band size: 48 kDa
    why is the actual band size different from the predicted?

    Primary incubation was 1 hour. Detected using chemiluminescence.

  • Immunocytochemistry/Immunofluorescence analysis of U251 cells labelling Casein Kinase 1 delta/CSNK1D with ab48031 at 10 µg/ml. Cells were paraformaldehyde fixed and permeabilized with 0.15% triton. Primary antibody icubation was for 1 hour followed by incubation with an Alexa Fluor® 488-conjugated secondary antibody at 2 µg/ml. DAPI nuclear counterstain was used.

    Negative control: Unimmunized goat IgG (10 µg/ml) followed by an Alexa Fluor® 488-conjugated secondary antibody (2 µg/ml).
