Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (CKS1_HUMAN | P61024)
molecular function
    GO:0016538    cyclin-dependent protein serine/threonine kinase regulator activity    Modulates the activity of a cyclin-dependent protein serine/threonine kinase, enzymes of the protein kinase family that are regulated through association with cyclins and other proteins.
    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).
biological process
    GO:0007049    cell cycle    The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
    GO:0051301    cell division    The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.
    GO:0008283    cell proliferation    The multiplication or reproduction of cells, resulting in the expansion of a cell population.
    GO:0000079    regulation of cyclin-dependent protein serine/threonine kinase activity    Any process that modulates the frequency, rate or extent of cyclin-dependent protein serine/threonine kinase activity.
cellular component
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
