Etoposide 167-176 dual specificity phosphatase 1 Homo sapiens 88-93 18434324-0 2008 Phosphorylation of protein kinase Cdelta on distinct tyrosine residues induces sustained activation of Erk1/2 via down-regulation of MKP-1: role in the apoptotic effect of etoposide. Etoposide 172-181 dual specificity phosphatase 1 Homo sapiens 133-138 18434324-9 2008 Etoposide induced down-regulation of kinase phosphatase-1 (MKP-1), which correlated with persistent phosphorylation of Erk1/2 and was dependent on the tyrosine phosphorylation of PKCdelta. Etoposide 0-9 dual specificity phosphatase 1 Homo sapiens 59-64 18434324-10 2008 Moreover, silencing of MKP-1 increased the phosphorylation of Erk1/2 and the apoptotic effect of etoposide. Etoposide 97-106 dual specificity phosphatase 1 Homo sapiens 23-28 18434324-11 2008 Etoposide induced polyubiquitylation and degradation of MKP-1 that was dependent on PKCdelta and on its tyrosine phosphorylation. Etoposide 0-9 dual specificity phosphatase 1 Homo sapiens 56-61
