Protein FULL name:

cellular tumor antigen p53 isoform a [Mus musculus].

Trp53 (Mus musculus) is product of expression of Trp53 gene.

FUNCTION: 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.

COFACTOR: Binds 1 zinc ion per subunit (By similarity).

SUBUNIT: Binds DNA as a homotetramer. Found in a complex with CABLES1 and TP73. Interacts with histone acetyltransferases EP300 and methyltransferases HRMT1L2 and CARM1, and recruits them to promoters. The C-terminus interacts with TAF1, when TAF1 is part of the TFIID complex. Interacts with HIPK1, HIPK2, AXIN1, and P53DINP1. Part of a complex consisting of TP53, HIPK2 and AXIN1. Interacts with WWOX. Interacts with USP7 and SYVN1. Interacts with HSP90AB1. Interacts with YWHAZ; the interaction enhances TP53 transcriptional activity. Phosphorylation of YWHAZ on 'Ser-58' inhibits this interaction (By similarity). Directly interacts with FBXO42; leading to ubiquination and degradation of TP53 (By similarity). Interacts with BANP, CDKN2AIP and E4F1. Interacts with CHD8, leading to recruit histone H1 and prevent transactivation activity.

INTERACTION: P03070:- (xeno); NbExp=6; IntAct=EBI-474016, EBI-617698; Q13315:ATM (xeno); NbExp=1; IntAct=EBI-474016, EBI-495465; O70445:Bard1; NbExp=1; IntAct=EBI-474016, EBI-1790207; Q07817-1:BCL2L1 (xeno); NbExp=2; IntAct=EBI-474016, EBI-287195; O96017:CHEK2 (xeno); NbExp=1; IntAct=EBI-474016, EBI-1180783; Q09472:EP300 (xeno); NbExp=1; IntAct=EBI-474016, EBI-447295; O54992:Mapkapk5; NbExp=1; IntAct=EBI-474016, EBI-1202132; P23804:Mdm2; NbExp=1; IntAct=EBI-474016, EBI-641788; Q8N2W9:PIAS4 (xeno); NbExp=2; IntAct=EBI-474016, EBI-473160; P63087-1:Ppp1cc; NbExp=1; IntAct=EBI-474016, EBI-450267; Q61466:Smarcd1; NbExp=1; IntAct=EBI-474016, EBI-371529; Q99986:VRK1 (xeno); NbExp=1; IntAct=EBI-474016, EBI-1769146;

SUBCELLULAR LOCATION: Cytoplasm (By similarity). Nucleus (By similarity). Endoplasmic reticulum (By similarity). Note=Interaction with BANP promotes nuclear localization (By similarity).

DOMAIN: The [KR]-[STA]-K motif is specifically recognized by the SETD7 methyltransferase (By similarity).

PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. Phosphorylated on Ser-15 upon ultraviolet irradiation; which is enhanced by interaction with BANP (By similarity). Phosphorylation on Ser residues mediates transcriptional activation. Phosphorylation at Ser-9 by HIPK4 increases repression activity on BIRC5 promoter. Phosphorylated on Thr-18 by VRK1, which may prevent the interaction with MDM2. Phosphorylated on Ser-386 following UV but not gamma irradiation. Phosphorylated by HIPK1.

PTM: Acetylated. Its deacetylation by SIRT1 impairs its ability to induce proapoptotic program and modulate cell senescence.

PTM: 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-285 and Lys-286, which leads to proteasomal degradation. Deubiquitinated by USP10, leading to stabilize it (By similarity).

PTM: Monomethylated at Lys-366 by SETD7, leading to stabilization and increased transcriptional activation. Monomethylated at Lys- 364 by SMYD2, leading to decreased DNA-binding activity and subsequent transcriptional regulation activity. Lys-366 monomethylation prevents interaction with SMYD2 and subsequent monomethylation at Lys-364 (By similarity).

PTM: Sumoylated by SUMO1 (By similarity).

PTM: Demethylation of di-methylated Lys-364 by KDM1A prevents interaction with TP53BP1 and represses TP53-mediated transcriptional activation (By similarity).

DISEASE: Note=p53 is found in increased amounts in a wide variety of transformed cells. p53 is frequently mutated or inactivated in many types of cancer.

SIMILARITY: Belongs to the p53 family.
