Overexpression of PRL phosphatases (PRL1, PRL2, and PRL3) has been found in a variety of late-stage tumors and their distant metastatic sites. Therefore, the oncogenic PRL phosphatases represent intriguing targets for cancer therapy. There is considerable interest in identifying small molecule inhibitors targeting PRLs as novel anticancer agents. However, it has been difficult to acquire phosphatase activity-based PRL inhibitors due to the unusual wide and shallow catalytic pockets of PRLs revealed by crystal structure studies. Here, we present a novel method to identify PRL1 inhibitors by targeting the PRL1 trimer interface and the procedure to characterize their biochemical and cellular activity.
