CC -!- FUNCTION: Acts as a tumor suppressor in many tumor types; induces
CC growth arrest or apoptosis depending on the physiological circumstances
CC and cell type. Involved in cell cycle regulation as a trans-activator
CC that acts to negatively regulate cell division by controlling a set of
CC genes required for this process. One of the activated genes is an
CC inhibitor of cyclin-dependent kinases. Apoptosis induction seems to be
CC mediated either by stimulation of BAX and FAS antigen expression, or by
CC repression of Bcl-2 expression. {ECO:0000256|RuleBase:RU003304}.

CC ECO:0000256|RuleBase:RU003304};
CC -!- SUBUNIT: Binds DNA as a homotetramer. {ECO:0000256|RuleBase:RU003304}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, microtubule organizing
CC center, centrosome {ECO:0000256|ARBA:ARBA00004300}. Cytoplasm
