Anti-acetyl-p53 Antibody (Lys373, Lys382)

Description

• General description: 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.
• Specificity: Recognizes p53 acetylated in vitro by recombinant p300, and for peptide containing acetyl-lysine 373 but not for the peptide containing acetyl-lysine 320.
• Immunogen: peptide of human p53 corresponding to amino acids 368-389 with a duplication of amino acids 376 and 377 (HLKSKACKGQSTSTSRHKACKLMFKTC) where ACK denotes acetyl-lysine
• Application: Detect acetyl-p53 (Lys373) with Anti-acetyl-p53 Antibody (Lys373, Lys382) (Rabbit Polyclonal Antibody), that has been shown to work in WB.
• Quality: routinely evaluated by an in vitro acetyl transferase assay on recombinant p300, HAT domain (Catalog #14-418)
• Target description: 53 kDa
