摘要: Wnt and its intracellular effector β-catenin regulate developmental oncogenic processes. Using expression cloning to identify novel components of the pathway, we isolated casein kinase Iɛ (CKIɛ). CKIɛ mimicked in inducing a secondary axis Xenopus, stabilizing β-catenin, stimulating gene transcription cells. Inhibition endogenous by kinase-defective or antisense-oligonucleotides attenuated signaling. was complex with axin other downstream including Dishevelled. appears be positive regulator pathway link between upstream signals complexes that β-catenin.
