We show that an inhibitor of protein phosphatases ( PPs ) PP1/PP2A , calyculin A , induces (i) phosphorylation of STAT3 on serine and threonine residues, (ii) inhibition of STAT3 tyrosine phosphorylation and DNA binding activity, and (iii) relocation of STAT3 from the nucleus to the cytoplasm .
 ( protein: protein phosphatases, None) , ( protein: STAT3, None) , ( protein: calyculin A, None) , ( protein: PPs, None) , ( protein: STAT3, None) , ( protein: STAT3, None) , ( protein: PP1/PP2A, None)
