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.
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:0007127    meiosis I    The first meiotic nuclear division in which homologous chromosomes are paired and segregated from each other, producing two haploid daughter nuclei.
    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.
