Regulatory mechanisms of PTEN

PTEN(Phosphatase and Tensin Homology deleted from Chromosome ten),a putative antioncogene,encodes a PTEN protein that has a dual specificity phosphatase activity with both protein phosphatase and lipid phosphatase,which regulates a variety of molecules through inhibiting the PI3K/Akt signaling pathway.Recently,some scholars dedicate to the modulation of PTEN,which demonstrates that PTEN can be regulated by multiple factors at the level of gene and protein.This review briefly summarizes up-to-date information about the modulation of PTEN and its mechanisms.
