Product Usage Information Western Blotting: 1:1000 Simple Western™: 1:10 - 1:50 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity CK1 Antibody detects endogenous levels of total casein kinase I-alpha 1 protein. This antibody may cross-react with casein kinase I-epsilon, casein kinase I-delta, and casein kinase I-gamma. Species Reactivity: Human, Mouse, Rat Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Arg170 of human casein kinase I isoform alpha protein. Antibodies are purified by protein A and peptide affinity chromatography. Background Casein Kinase I (CK1 or CKI) is the name given to a family of kinases consisting of multiple isoforms (alpha, alpha prime, beta, gamma 1-3, delta, and epsilon) with a conserved N-terminal kinase domain and a variable C-terminal sequence that determines subcellular localization and regulates enzyme activity (1-3). Indeed, multiple inhibitory autophosphorylation sites have been identified near the C terminus of CK1 epsilon (3). This ubiquitously expressed family of protein kinases has been implicated in multiple processes, including DNA repair, cell morphology, and Wnt signaling (4). Perhaps the best understood role of CK1 is to provide the priming phosphorylation of beta-Catenin at Ser45 to produce the consensus GSK-3 substrate motif (S/T-X-X-X-pS) (4).
