The full p28 peptide sequence is LSTAADMQGVVTDGMASGLDKDYLKPDD. This specific arrangement of amino acids dictates the peptide's unique properties, including its amphipathic nature and its capacity to adopt an α-helical structure. These characteristics are fundamental to its function as a cell penetrating peptide, allowing it to effectively enter cells, including cancer cells. Research has also identified specific regions within the p28 peptide that are critical for its activity.2022年7月21日—We utilized a tumor-targeting cell-penetration peptide,p28, as a therapeutic agent to improve the efficacy of a current chemotherapeutic agent for GBM. For instance, p28 peptide residues in the sequence range of 1-4, 7-11, and 22-23 have been implicated in masking the hydrophobic pocket of HDM2, a protein that can promote the degradation of p53.

One of the key mechanisms by which p28 exerts its anticancer effects is by binding to p53. This interaction is not straightforward; rather, p28 binds to a specific motif within the DNA binding domain (DBD) of p53.Studying the Interaction Mechanism of Azurin-Derived ... This binding event is significant because it can inhibit COP1-mediated degradation of p53, thereby increasing intracellular levels of this vital tumor suppressorAzurin p28 peptide is a28 amino acid fragment of azurin(amino acids 50-77). The peptide is preferentially taken up by human breast cancer cell lines via .... This disruption of the p53-HDM2 interactions is a critical aspect of p28's mechanism of action. Some studies suggest that the COOH terminal 10–12 aa of p28 play a role in inhibiting cell growth and promoting apoptosis, further highlighting the importance of the precise amino acid arrangement.作者：A Joy·2026—Thep28 peptide residues in the sequence range of 1–4, 7–11, and 22–23are involved in masking the hydrophobic pocket of HDM2 by interacting ...

The origin of the p28 peptide is from the bacterial protein azurin, which is a redox proteinThis GPI signalsequencefunctions poorly in heterologous eukaryotic cells, causing CSP retention within internal cell organelles during genetic immunization.. The specific fragment used as a therapeutic agent comprises amino acids 50-77 of azurin. This azurin-derived cell-penetrating peptide p28 is a water-soluble, amphipathic molecule with a molecular weight of approximately 2.Noncationic Peptides Obtained From Azurin Preferentially ...9 kDa.作者：AR Garizo·2021·被引用次数：62—Among them,p28(28 amino acids; 2.8 kDa), a CPP derived from the bacterial protein azurin (128 amino acids; 14 kDa), is an interesting molecule ... Its ability to be preferentially taken up by human cancer cell lines, including breast cancer cell lines, is a key attribute. The p28 peptide derived from Pseudomonas aeruginosa azurin has shown anticancer activity after binding to the p53 protein and has progressed into Phase I clinical trials, underscoring its therapeutic relevance.

Further exploration of the p28 peptide sequence has revealed that specific modifications can be made to enhance its interaction with p53. Researchers are investigating how to rationally modify the amino acid sequence of p28 to further boost this interactionAzurin-Based Peptide p28 Arrests the p53-HDM2 Interactions. For example, the sequence Leu-Ser-Thr-Ala-Ala-Asp-Met-Gln-Gly-Val-Val-Thr-Asp-Gly-Met-Ala is a representation of the peptide's amino acid composition, and variations or additions, such as synthesizing a new p28 peptide sequence by adding a cysteine to the hydrophilic region, are being explored to optimize its function.
