p2a-self-cleaving-peptide The p28 azurin peptide sequence has emerged as a significant area of research within the field of oncology, offering a novel approach to combating cancer. This peptide, a 28-amino acid fragment derived from the bacterial protein azurin, specifically amino acids 50-77, has demonstrated remarkable potential due to its ability to penetrate tumor cells and exert antitumor effects.2011年6月28日—P28(University of Illinois at Chicago), a first-in-class inhibitor of the ubiquitination of cellular tumor antigen p53, may represent a ... The underlying mechanism often involves interactions with critical cellular regulators like p53, a vital tumor suppressorSolution structure of the anticancer p28 peptide in ....

Azurin, a 128-amino acid Cupredoxin secreted by opportunistic pathogens such as *Pseudomonas aeruginosa*, serves as the source for this potent therapeutic agent.discovery-of-azurin-like-anticancer-bacteriocins-from- ... The specific p28 sequence is LSTAADMQGVVTDGMASGLDKDYLKPDD, with a molecular weight of approximately 2914.18 Da and molecular formula C122H197N31O47S2. This azurin sequence fragment, referred to as p28, exhibits amphipathic properties, contributing to its cell-penetrating capabilities.

One of the key mechanisms by which the p28 peptide functions is by inhibiting the interaction between p53 and its negative regulators, such as Cop1 and HDM2. The p28:p53 complex formation is crucial, as it can reduce the proteasomal degradation of p53. By stabilizing p53, the p28 peptide enhances the tumor-suppressive functions of this critical protein, ultimately leading to programmed cell death, or apoptosis, in cancer cells.Azurin - an overview Research has indicated that specific residues within the p28 sequence, such as those in positions 1-4, 7-11, and 22-23, are involved in masking the hydrophobic pocket of HDM2, thereby disrupting their bindingOur findings reveal that by blocking HDM2's binding sites,p28helps maintain p53's transcriptional activity, thus enhancing its tumor-suppressive functions, ....

The therapeutic advantages of the p28 peptide are multifaceted. Its ability to preferentially enter human breast cancer cell lines and other tumor types makes it a targeted therapeutic agent. Unlike some conventional treatments, p28 aims to specifically disrupt cancer cell proliferation. The order of amino acids in the p28 sequence is critical for its biological activity and its ability to interact with target proteins.Azurin-Based Peptide p28 Arrests the p53-HDM2 Interactions Scientists have explored various modifications and purities, with Azurin p28 peptide TFA often cited with a purity of ≥95%.
