: It is used to study how p53-dependent pathways can be "re-awakened" in cancer cells or protected in normal cells during stress. By manipulating the APAK-p53 bond, researchers can investigate the protein’s role in tumor survival and its potential as a therapeutic target. Applications in Preclinical Research
: When DNA damage occurs, the ATM (ataxia-telangiectasia mutated) kinase phosphorylates APAK at specific sites (e.g., Ser68), causing it to dissociate from p53. This release allows p53 to activate genes like p53AIP1 , which initiate apoptosis. Characteristics of APAK-212 APAK-212
: It often incorporates specific domains from the natural APAK protein, such as the zinc finger motifs or the KRAB domain, to target the p53 interaction interface. : It is used to study how p53-dependent
The construct is a research-grade tool designed to mimic or interfere with these interactions. Based on its classification in preclinical literature, it typically features: This release allows p53 to activate genes like
: Under normal (unstressed) conditions, APAK binds to p53 and recruits a corepressor complex (KAP-1 and HDAC1) to inhibit p53’s pro-apoptotic activity.
