"Casein kinase 1alpha (CK1alpha) suppresses cell migration and invasion through inhibition of chromobox homolog 4 (CBX4). CK1alpha phosphorylates CBX4 at T437 and facilitates its ubiquitination at both K178 and K280 and subsequent degradation by CHIP. There is a reverse correlation between CK1alpha and CBX4 in osteosarcoma tissues and CK1alpha is a valuable marker to predict clinical outcomes in osteosarcoma patients w..."xsd:string
