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|ARBA:ARBA00024672}.
CC -!- FUNCTION: Participates in the apoptotic response to DNA damage.
CC Isoforms containing the transactivation domain are pro-apoptotic,
CC isoforms lacking the domain are anti-apoptotic and block the function
CC of p53 and transactivating p73 isoforms. May be a tumor suppressor
CC protein. {ECO:0000256|RuleBase:RU003304}.

CC -!- SUBUNIT: Binds DNA as a homotetramer. {ECO:0000256|ARBA:ARBA00011393}.
CC -!- SUBUNIT: Found in a complex with p53/TP53 and CABLES1.
