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 (By similarity). {ECO:0000250}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- SUBUNIT: Binds DNA as a homotetramer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the p53 family. {ECO:0000305}.
