Functioni

Acts as a tumor suppressor in many tumor types; induces growth arrest or apoptosis depending on the physiological circumstances and cell type. Involved in cell cycle regulation as a trans-activator that acts to negatively regulate cell division by controlling a set of genes required for this process. One of the activated genes is an inhibitor of cyclin-dependent kinases. Apoptosis induction seems to be mediated either by stimulation of BAX and FAS antigen expression, or by repression of Bcl-2 expression. In cooperation with mitochondrial PPIF is involved in activating oxidative stress-induced necrosis; the function is largely independent of transcription. Prevents CDK7 kinase activity when associated to CAK complex in response to DNA damage, thus stopping cell cycle progression. Induces the transcription of long intergenic non-coding RNA p21 (lincRNA-p21) and lincRNA-Mkln1. LincRNA-p21 participates in TP53-dependent transcriptional repression leading to apoptosis and seem to have to effect on cell-cycle regulation. Regulates the circadian clock by repressing CLOCK-ARNTL/BMAL1-mediated transcriptional activation of PER2.By similarity

Post-translational modificationi

Phosphorylation on Ser residues mediates transcriptional activation. Phosphorylated on Thr-18 by VRK1, which may prevent the interaction with MDM2. Phosphorylated on Ser-20 by CHEK2 in response to DNA damage, which prevents ubiquitination by MDM2. Phosphorylated on Ser-20 by PLK3 in response to reactive oxygen species (ROS), promoting p53/TP53-mediated apoptosis. Phosphorylated on Ser-33 by CDK7 in a CAK complex in response to DNA damage. Phosphorylated by HIPK1. Phosphorylated on Ser-385 following UV but not gamma irradiation. Phosphorylated on Ser-15 upon ultraviolet irradiation; which is enhanced by interaction with BANP. Stabilized by CDK5-mediated phosphorylation in response to genotoxic and oxidative stresses at Ser-15 and Ser-33, leading to accumulation of p53/TP53, particularly in the nucleus, thus inducing the transactivation of p53/TP53 target genes. Phosphorylated at Ser-308 and Ser-385 by CDK2 in response to DNA-damage (By similarity).By similarity
Acetylated. Its deacetylation by SIRT1 impairs its ability to induce proapoptotic program and modulate cell senescence. Deacetylation by SIRT2 impairs its ability to induce transcription activation in a AKT-dependent manner (By similarity).By similarity
Ubiquitinated by MDM2 and SYVN1, which leads to proteasomal degradation. Ubiquitinated by RFWD3, which works in cooperation with MDM2 and may catalyze the formation of short polyubiquitin chains on p53/TP53 that are not targeted to the proteasome. Ubiquitinated by MKRN1 at Lys-284 and Lys-285, which leads to proteasomal degradation. Deubiquitinated by USP10, leading to stabilize it. Ubiquitinated by TRIM24 and RFFL, which leads to proteasomal degradation. Ubiquitination by TOPORS induces degradation. Deubiquitination by USP7, leading to stabilize it. Ubiquitinated by RFWD2, which leads to proteasomal degradation. Ubiquitination and subsequent proteasomal degradation is negatively regulated by CCAR2 (By similarity).By similarity
Monomethylated at Lys-365 by SETD7, leading to stabilization and increased transcriptional activation. Monomethylated at Lys-363 by SMYD2, leading to decreased DNA-binding activity and subsequent transcriptional regulation activity. Lys-365 monomethylation prevents interaction with SMYD2 and subsequent monomethylation at Lys-363. Dimethylated at Lys-366 by EHMT1 and EHMT2. Monomethylated at Lys-375 by KMT5A, promoting interaction with L3MBTL1 and leading to repress transcriptional activity. Demethylation of dimethylated Lys-363 by KDM1A prevents interaction with TP53BP1 and represses TP53-mediated transcriptional activation (By similarity).By similarity
Sumoylated with SUMO1. Sumoylated at Lys-379 by UBC9 (By similarity).By similarity
