CC -!- FUNCTION: Acts as a sequence specific DNA binding transcriptional
CC activator or repressor. The isoforms contain a varying set of
CC transactivation and auto-regulating transactivation inhibiting domains
CC thus showing an isoform specific activity. May be required in
CC conjunction with TP73/p73 for initiation of p53/TP53 dependent
CC apoptosis in response to genotoxic insults and the presence of
CC activated oncogenes. {ECO:0000256|RuleBase:RU003304}.
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 -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|PIRSR:PIRSR602117-1,
CC ECO:0000256|RuleBase:RU003304};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|PIRSR:PIRSR602117-1,
CC ECO:0000256|RuleBase:RU003304};
CC -!- SUBUNIT: Binds DNA as a homotetramer. Isoform composition of the
CC tetramer may determine transactivation activity.
CC {ECO:0000256|RuleBase:RU003304}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123,
CC ECO:0000256|RuleBase:RU003304}.
CC -!- SIMILARITY: Belongs to the p53 family. {ECO:0000256|ARBA:ARBA00006167,
CC ECO:0000256|RuleBase:RU003304}.
