General annotation (Comments)
Essential serine/threonine-protein kinase that regulates diverse cellular growth and survival processes including Wnt signaling, DNA repair and circadian rhythms. It can phosphorylate a large number of proteins. Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. Phosphorylates connexin-43/GJA1, MAP1A, SNAPIN, MAPT/TAU, TOP2A, DCK, HIF1A, EIF6, p53/TP53, DVL2, DVL3, ESR1, AIB1/NCOA3, DNMT1, PKD2, YAP1, PER1 and PER2. Central component of the circadian clock. In balance with PP1, determines the circadian period length through the regulation of the speed and rhythmicity of PER1 and PER2 phospohorylation. Controls PER1 and PER2 nuclear transport and degradation. YAP1 phosphorylation promotes its SCF(beta-TRCP) E3 ubiquitin ligase-mediated ubiquitination and subsequent degradation. DNMT1 phosphorylation reduces its DNA-binding activity. Phosphorylation of ESR1 and AIB1/NCOA3 stimulates their activity and coactivation. Phosphorylation of DVL2 and DVL3 regulates WNT3A signaling pathway that controls neurite outgrowth. EIF6 phosphorylation promotes its nuclear export. Triggers down-regulation of dopamine receptors in the forebrain. Activates DCK in vitro by phosphorylation. TOP2A phosphorylation favors DNA cleavable complex formation. May regulate the formation of the mitotic spindle apparatus in extravillous trophoblast. Modulates connexin-43/GJA1 gap junction assembly by phosphorylation. Probably involved in lymphocyte physiology. Regulates fast synaptic transmission mediated by glutamate By similarity.
ATP + a protein = ADP + a phosphoprotein.
ATP + [tau protein] = ADP + [tau protein] phosphate.
Exhibits substrate-dependent heparin activation. Drug-mediated inhibition leads to a delay of the oscillations with the magnitude of this effect dependent upon the timing of drug administration. Inhibited by phosphorylation By similarity.
Binds to DNMT1 and MAP1A. Monomer. Component of the circadian core oscillator, which includes the CRY proteins, CLOCK, or NPAS2, ARTNL/BMAL1 or ARTNL2/BMAL2, CSNK1D and/or CSNK1E, TIMELESS and the PER proteins. Interacts directly with PER1 and PER2 which may lead to their degradation. Interacts with MAPT/TAU, SNAPIN, DBNDD2, AIB1/NCOA3 and ESR1. AKAP9/AKAP450 binding promotes centrosomal subcellular location. Binds to tubulins in mitotic cells upon DNA damage By similarity.
Cytoplasm By similarity. Nucleus By similarity. Cytoplasm › cytoskeleton › microtubule organizing center › centrosome By similarity. Cytoplasm › perinuclear region By similarity. Cell membrane By similarity. Cytoplasm › cytoskeleton › spindle By similarity. Golgi apparatus By similarity. Note: Localized at mitotic spindle microtubules, and at the centrosomes and interphase in interphase cells. Recruited to the spindle apparatus and the centrosomes in response to DNA-damage. Correct subcellular localization requires kinase activity By similarity.
Autophosphorylated on serine and threonine residues; this autophosphorylation represses activity. Reactivated by phosphatase-mediated dephosphorylation. May be dephosphorylated by PP1 By similarity.
Contains 1 protein kinase domain.
