Inhibition of Phosphatases
Pervanadate primarily exerts its effects through the inhibition of phosphatases, a group of enzymes responsible for removing phosphate groups from proteins. This process is essential for numerous cellular functions, including signal transduction, cell growth, and apoptosis. When phosphatases are inhibited, the phosphorylation state of proteins changes, often leading to altered cellular responses. This inhibition can stabilize signaling pathways that would otherwise be downregulated, resulting in significant alterations in gene expression and cell behavior.
The way pervanadate inhibits phosphatases is through the formation of stable complexes with the active site of these enzymes.
