Cyclic peptides have been expected to be one of the modalities of intracellular protein-protein interaction (PPI) inhibitors, but they are generally known to have low cell membrane permeability.

MDM2-ALT1 and MDMX-ALT2 interact with full-length MDM2 and MDMX.
A. Full-length MDM2 is encoded by exons 3 to 12 of the MDM2 gene and consists of the N-terminal p53-binding domain, the nuclear localization (NLS) and export signals (NES), the central ARF binding and Zinc finger domains and the C-terminal RING domain ...

MDM2 Promotes Ubiquitination and Degradation of MDMX [PDF]
The p53 tumor suppressor is regulated by MDM2-mediated ubiquitination and degradation. Mitogenic signals activate p53 by induction of ARF expression, which inhibits p53 ubiquitination by MDM2. Recent studies showed that the MDM2 homolog MDMX is also an important regulator of p53.

Introduction Many human breast cancers overexpress the E3 ubiquitin ligase MDM2 and its homolog MDMX. Expression of MDM2 and MDMX occurs in estrogen receptor α-positive (ERα+) breast cancer and triple-negative breast cancer (TNBC).

Therapeutic peptide self‐assembly is governed by multiple non‐covalent interactions, enabling the construction of diverse supramolecular structures. These self‐assembled systems can be engineered through spontaneous self‐assembly of monomers, co‐assembly, or stimulus‐responsive strategies to improve tumor delivery efficiency.

RPL37, RPS15, and RPS20 bind to and regulate MdmX levels.
(a–c) Association of RPs and MdmX. H1299 cells were transfected with HA-MdmX (0.5 µg), Myc-RP (1.2 µg), or both. (GFP was added as a control for transfection efficiency.) Ectopic MdmX and RP levels were detected by immunoblotting with α-MdmX and α-Myc ...

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

rHSA-P53i and rHSA-PMI bind to MDM2 and MDMX.
To detect the interaction between MDM2/MDMX and rHSA fusion proteins, 4 µg each of biotinylated rHSA (lane 1), rHSA-P53i (lane 2), or rHSA-PMI (lane 3) were added to 200 µg of SJSA-1 whole cell lysate.

An α‐helical peptide, TAB12, designed to mimic the TRIM28 binding interface, competitively disrupts the TRIM28‐BRD7 interaction, thereby blocking ubiquitin‐mediated degradation of the tumor suppressor BRD7. This stabilization unleashes potent anti‐tumor effects across multiple tumor types with a favorable safety profile, offering a feasible strategy ...
