Lockdown is a selective, reversible and non-competitive inhibitor of the integrin phosphatase PPM1F (IC50=16.37 uM), blocks cancer cell invasion.Lockdown acts in a dose-dependent, allosteric manner with high selectivity for PPM1F.Lockdown does not inhibit other protein phosphatases (PTP1P, PTPRJ, PP5) in vitro and does not induce additional phenotypes in PPM1F knockout cells.Lockdown fully re-capitulated the phenotype of PPM1F-deficient cells, increased phosphorylation of PPM1F substrates and corruption of integrin-dependent cellular processes in Lockdown treated glioblastoma cells.Phosphatase PPM1F is a regulator of cell adhesion by fine-tuning integrin activity and actin cytoskeleton structures. Elevated expression of this enzyme in human tumors is associated with high invasiveness, enhanced metastasis, and poor prognosis.
