- _4 value "Interestingly, PLZF and GATA1 proteins coimmunoprecipitate in PLZF-expressing TF1 cells: enforced expression of both PLZF and GATA1 in TF1 cells results in increased upregulation of megakaryocytic markers, as compared to exogenous PLZF or GATA1 alone, suggesting a functional role for the PLZF/GATA1 complex. Our data indicate that PLZF plays a significant stimulatory role in megakaryocytic development, seemingly mediated in part by induction of TpoR expression at transcriptional level. This stimulatory effect is potentiated by physical interaction of PLZF and GATA1, which are possibly assembled in a multiprotein transcriptional complex. PLZF interacts with the transcription factor GATA1 and stimulates the thrombopoietin receptor (TpoR) gene transcription, by activating a promoter region which contains a potential DNA binding site for the PLZF protein." provenance.
