== Publication Abstract from PubMed ==
The three-dimensional structure for the catalytic region of the mammalian protein kinase, casein kinase I delta (CKI delta), has been solved by X-ray crystallography to a resolution of 2.3 A. A truncation mutant of CKI delta lacking the C-terminal autoinhibitory region was expressed in Escherichia coli, purified, and crystallized. The structure was solved by molecular replacement using the crystal structure of the catalytic domain of a CKI homolog from Schizosaccharomyces pombe, Cki1. A tungstate derivative confirmed the initial molecular replacement solution and identified an anion binding site which may contribute to the unique substrate specificity of CKI. Like other protein kinases, the catalytic domain of CKI is composed of two lobes with a cleft between them for binding ATP. Comparison of the mammalian and yeast CKI structures suggests that a rotation of the N-terminal domain occurs upon ATP binding. This domain motion is similar, but not identical, to that observed in cAMP-dependent protein kinase upon binding ATP. Although Cki1 has many similarities to CKI delta over the catalytic domain, these two forms of CKI likely perform different functions in vivo. Relating the primary sequences of other CKI enzymes to the three-dimensional architecture of CKI delta reveals a catalytic face that is especially conserved among the subset of CKI family members associated with the regulation of DNA repair.

Function

KC1D_RAT 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. May act as a negative regulator of circadian rhythmicity by phosphorylating PER1 and PER2, leading to retain PER1 in the cytoplasm. 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).[1]
