This research aims to investigate how cancer-associated mutations in MDM2 affect its interaction with ribosomal proteins and p53 degradation.
Investigated the interaction of MDM2 mutations with ribosomal proteins in vitro.
Analyzed the impact of MDM2 zinc finger mutations on p53 degradation and transcriptional activity.
Assessed nuclear export and proteasomal degradation of MDM2 mutants.
Zinc finger mutations in MDM2 disrupted its binding with ribosomal proteins L5 and L11.
The MDM2 zinc finger mutant showed impaired nuclear export and proteasomal degradation of p53.
Unlike wild-type MDM2, the zinc finger mutant did not undergo L11-mediated inhibition of p53-suppressive activity.
