p53 is a DNA-binding, oligomerization domain and transcription activation domain-containing tumor suppressor that upregulates growth arrest and apoptosis-related genes in response to stress signals, thereby influencing programmed cell death, cell differentiation and cell cycle control mechanisms. p53 localizes to the nucleus yet can be chaperoned to the cytoplasm by the negative regulator MDM2, an E3 ubiquitin ligase that is upregulated in the presence of active p53, where MDM2 polyubiquitinates p53 for proteasome targeting. p53 can assemble into tetramers in the absence of DNA, fluctuates between latent and active (DNA-binding) conformations, and is differentially activated through posttranslational modifications including phosphorylation and acetylation. Mutations in the DNA-binding domain (DBD) (amino acids 110-286) of p53 can compromise energetically favorable association with cis elements and are implicated in several human cancers.

53 kDa

peptide corresponding to amino acids 367-379 of human p53 (SHLKSKACKGQSTSR, where ACK denotes acetyl-lysine).

Anti-acetyl-p53 (Lys373) Antibody is a Rabbit Polyclonal Antibody for detection of acetyl-p53 (Lys373) also known as Antigen NY-CO-13, Phosphoprotein p53, Tumor suppressor p53, p53 antigen & has been tested in IP & WB.

Recognizes p53 acetylated in vitro by recombinant p300, and for peptide containing acetyl-lysine 373 but not for the peptide containing acetyl-lysine 320; modest cross-reactivity for p53 acetylated in vitro by recombinant PCAF.
