Abstract

The activity of hematopoietic factor GATA-1 is modulated through p300/CBP-mediated acetylation and FOG-1 mediated indirect interaction with HDAC1/2 containing NuRD complex. Although GATA-1 acetylation is implicated in GATA-1 activation, the role of deacetylation is not studied. Here, we found that the FOG-1/NuRD does not deacetylate GATA-1. However, HDAC1/2 can directly bind and deacetylate GATA-1. Two arginine residues within the GATA-1 linker region mediates direct interaction with HDAC1. The arginine to alanine mutation (2RA) blocks GATA-1 deacetylation and fails to induce erythroid differentiation. Gene expression profiling and ChIP-seq analysis further demonstrate the importance of GATA-1 deacetylation for gene activation and chromatin recruitment. GATA-12RA knock-in (KI) mice suffer mild anemia and thrombocytopenia with accumulation of immature erythrocytes and megakaryocytes in bone marrow and spleen. Single cell RNA-seq analysis of Lin- cKit+ (LK) cells further reveal a profound change in cell subpopulations and signature gene expression patterns in HSC, myeloid progenitors, and erythroid/megakaryocyte clusters in KI mice. Thus, GATA-1 deacetylation and its interaction with HDAC1 modulates GATA-1 chromatin binding and transcriptional activity that control erythroid/megakaryocyte commitment and differentiation.
