This precise arrangement of amino acids dictates its three-dimensional structure and its ability to interact with cellular targets.

Mechanism of Action: Targeting p53

A key mechanism by which the p28 azurin peptide exerts its anticancer effects is by interfering with the interaction between p53 and its negative regulator, HDM2 (or its homolog COP1). HDM2 normally targets p53 for degradation, thereby limiting its tumor-suppressive functions. The p28 peptide can bind to p53, or to HDM2, disrupting this interaction and preventing the proteasomal degradation of p53. This stabilization of p53 leads to its accumulation in cancer cells, where it can activate cell cycle arrest and apoptosis, ultimately leading to the elimination of cancerous cellsAzurin and its protein subunit P28 as an alternative .... The formation of a p28:p53 complex is a central aspect of this mechanism.Azurin - an overview
