Biochem/physiol Actions

Human p53 protein is composed of 393 amino acid residues with several distinct regions. The N-terminal activation domain allows p53 protein to recruit the basal transcription machinery and activate the expression of target genes, whereas the core domain binds to target DNA in a sequence-specific manner and the majority of mutations found in human tumors occur in the region of the gene encoding this domain. The C-terminal domain is composed of predominantly basic residues and modification of the C-terminal basic domain, including acetylation, glycosylation and phosphorylation, is an essential mechanism for regulating p53 function.
