Abstract

The zinc finger transcription factor GATA-2 plays a critical role in the survival and proliferation of hematopoietic stem cells. This study examined the interaction of GATA-2 with histone deacetylases (HDACs) to define the involvement of HDACs in the regulation of GATA-2 function. GATA-2 directly associates with HDAC3 but not with HDAC1. Consistent with this, HDAC3 suppressed the transcriptional potential of GATA-2, whereas HDAC1 did not affect GATA-2-dependent transcription. Results further demonstrated that GATA-2 and HDAC3 colocalized in the nucleus. These results identify GATA-2 as a nuclear target for HDAC3-mediated repression. Furthermore, GATA-2 also directly associated with HDAC5 but not with other class II HDACs examined, that is, HDAC4 and HDAC6. This is the first demonstration that a tissue-specific transcription factor directly and selectively interacts with HDAC3 and HDAC5 among HDAC family members.
