11865049	We show here that mPer proteins, negative limbs of the autoregulatory loop, are specific substrates for CKIepsilon and CKIdelta. The CKI phosphorylation of mPer1 and mPer3 proteins results in their rapid degradation, which is dependent on the ubiquitin-proteasome pathway.

29789297	We identified members of the FAM83 family of proteins as partners of CK1 in cells. All eight members of the FAM83 family (FAM83A–H) interacted with the α and α-like isoforms of CK1; FAM83A, -B, -E, and -H also interacted with the δ and ε isoforms of CK1. The intrinsic catalytic activity of CK1 is not affected by or required for the association of CK1 with FAM83 proteins. Our findings imply that the DUF1669 domains of FAM83 proteins anchor CK1 α, α-like, δ, and ε isoforms in specific subcellular compartments and potentially mediate their association with substrates.

12000790	We conclude that a major role of axin in the wnt is to provide the kinase activity that initiates the betBeta-catenin phosphorylation cascade at s45. This process is mediated by cki, the alfa, delta, or ? Isoform, all detected in association with axin by lc/ms.

Function	Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. Can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates DVL1 and DVL2. 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 phosphorylation. Controls PER1 and PER2 nuclear transport and degradation. Inhibits cytokine-induced granuloytic differentiation.
