Chain A,B,D,E,G,H,J,K   (CSK2B_XENLA | P28021)
molecular function
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0019887    protein kinase regulator activity    Modulates the activity of a protein kinase, an enzyme which phosphorylates a protein.
biological process
    GO:0016055    Wnt signaling pathway    The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell and ending with a change in cell state.
    GO:0045859    regulation of protein kinase activity    Any process that modulates the frequency, rate or extent of protein kinase activity.
cellular component
    GO:0031519    PcG protein complex    A chromatin-associated multiprotein complex containing Polycomb Group proteins. In Drosophila, Polycomb group proteins are involved in the long-term maintenance of gene repression, and PcG protein complexes associate with Polycomb group response elements (PREs) in target genes to regulate higher-order chromatin structure.
    GO:0005956    protein kinase CK2 complex    A protein complex that possesses protein serine/threonine kinase activity, and contains two catalytic alpha subunits and two regulatory beta subunits. Protein kinase CK2 complexes are found in nearly every subcellular compartment, and can phosphorylate many protein substrates in addition to casein.
