CC -!- FUNCTION: Casein kinases are operationally defined by their
CC preferential utilization of acidic proteins such as caseins as
CC substrates. It can phosphorylate a large number of proteins.
CC Participates in Wnt signaling. Phosphorylates CTNNB1 at 'Ser-45'. May
CC phosphorylate PER1 and PER2. May play a role in segregating chromosomes
CC during mitosis. May play a role in keratin cytoskeleton disassembly and
CC thereby, it may regulate epithelial cell migration (By similarity).
