  • a transactivation domain located in the N terminus (N-TAD) and two zinc finger domains located in the middle of the molecule
  • C-terminal zinc finger (C-finger) essential for GATA1 function, since it is responsible for the recognition of the GATA consensus sequence and consequent binding to DNA, C-terminal and this region of GATA1 indeed functions as a transactivation domain
  • both N-TAD and C-TAD retain redundant as well as specific activities for proper hematopoiesis
  • GATA zinc finger transcription factor family

    intracellular,nucleus,nucleoplasm,nuclear bodies
  • associated with a special class of nuclear bodies
  • export of GATA1 from the endoplasmic reticulum (ER) is contingent on its interaction with the COPII (coatomer protein-II) coat subunit SEC24D
  • basic FUNCTION
  • regulation of erythroid development and their critical genes, i.e the globin genes
  • playing a role in osteoblast differentiation
  • essential for terminal erythroid and megakaryocytic differentiation
  • involved in regulation of the switch from fetal to adult hemoglobin and in osteoblast differentiation
  • required with FLI1 for development of megakaryocytes
  • playing an essential role for normal erythropoiesis, also in eosinophil development, in the terminal differentiation of mast cells
  • under the influence of GATA1, TRIM35 relocates from cytoplasmic granules to the nucleus where it associates with both ZFPM1 and GATA1
  • with ZNF148, cooccupy cis-regulatory elements of certain erythroid and megakaryocyte-specific genes, including an enhancer of the GATA1 gene itself
  • activating transcription of the erythropoietin receptor (EPOR)
  • may be playing a role in globin switching
  • regulating the angiogenic factor AGGF1
  • master regulator of terminal differentiation of erythroid precursors
  • continuous presence of GATA1,ZFPM1, and NuRD is required to maintain lineage fidelity throughout megakaryocyte-erythroid ontogeny
  • role of GATA1 and IGF signaling in fetal megakaryopoiesis and leukemogenesis in Down syndrome
  • is a major determinant of BRD3 recruitment to genomic targets within chromatin
  • ZFPM1 is required for the formation of all committed Mk- and E-lineage progenitors, whereas GATA1 was observed to be specifically required for E-lineage commitment
  • regulates the expression of a cluster of genes important for hematopoietic cell differentiation toward erythroid and megakaryocytic lineage
  • mitotic GATA1 target genes tend to reactivate more rapidly upon entry into G1 than genes from which GATA1 dissociates
  • unlike GATA1, which inhibits cell division, ZFPM2 promotes proliferation
  • CELLULAR PROCESS nucleotide, transcription, regulation
    a component part of the DNA-binding complex containing LMO2, LDB1, TAL1, and GATA1
    DNA binding sequence
    small molecule
  • FOG1 (in both megakaryocyte and erythrocyte development
  • interacting with ZNF145, coactivating thrombopoetin receptor and inducing megakaryocyte development
  • binding to the beta-globin locus
  • mediating with NFE2 the erythrocyte expression of alpha-spectrin
  • with Sp1 or EKLF (may play a crucial role in bringing regulatory elements such as enhancers in proximity to promoters by promoting the formation of DNA loops)
  • interacting with MED1(acting as a coactivator in erythroid development)
  • interacting with SPI1 (Ets domain of SPI1 and the GATA1 C-terminal zinc finger (CF) form a low affinity interaction in which specific regions of each protein are implicated)
  • GATA1 specifically associates with BCL11A in erythroid cells
  • combinatorial effect of Ikaros and GATA1 impairs close proximity between the locus control region and the gamma-globin genes and might represent an important mechanism of gene regulation during hematopoiesis
  • direct interaction of GATA1 with EHZF was demonstrated(EHZF modulates erythroid cell differentiation through direct binding with GATA1)
  • direct transcriptional target of TAp73alpha
  • HMG2B potentiates GATA1-dependent transcription of GFI1B by POU5F1 and thereby controls erythroid differentiation
  • interaction between GATA1 and ZFPM1 is critical for the development of both erythroid and megakaryocytic cell lineages
  • functional relationship between GATA1 and DMRT1, coexpressed in Sertoli cells
  • is a functionally important target gene of SUPT5H
  • interacting with BRD3, and this interaction is essential for the targeting of GATA1 to chromatin
  • BRD3 binds via its first bromodomain (BD1) to GATA1 in an acetylation-dependent manner
  • GATA1 and its cofactor ZFPM1 are required for the differentiation of erythrocytes and megakaryocytes
  • exogenous expression of ZFPM1 in mast cells leads to displacement of GATA1 from mast cell-specific genes and causes their downregulation
  • utilizes IKAROS and polycomb repressive complex 2 to suppress HES1 and to promote erythropoiesis
  • GATA2 and GATA1 positively and negatively control human IL1RL1 gene transcription, respectively and are involved in IL1RL1 transcription levels in primary basophils maintained in the presence of IL3
  • CDC6 expression is regulated by lineage-specific transcription factor GATA1
  • GATA1 coregulators ZFPM1 and TAL1 dissociate from mitotic chromatin, suggesting that GATA1 functions as platform for their postmitotic recruitment
  • CEBPA and/or GATA1 directly suppress the expression of DACH1 through binding to the promoter region
  • TAL1 associates with GATA1, GATA2, lim-only protein LMO2, and LDB1 in a multimeric complex to regulate erythroid transcription
  • TAL1 can recruit GATA1 and increase GATA1 binding to the EPOR promoter region to stimulate gene expression
  • MED1 is a context-dependent GATA1 coregulator, and also exerts specialized functions in erythroid cells to control GATA1-independent, cell-type-specific genes, which include candidate regulators of erythroid cell development and function
  • GATA1-dependent looping mechanisms may facilitate the conservation of TAL1 regulation despite cis-regulatory remodeling during vertebrate evolution
  • PSTPIP2 is a GATA1-repressed gene that controls megakaryopoiesis
  • GATA1 and TAL1 are bound to the regulatory regions of TFDP2 and upregulate its expression
  • SPI1 and GATA1 transactivate FCER1A
  • GATA1/FOXO3 repressed expression of EXOSC8, a pivotal component of the exosome complex, which mediates RNA surveillance and epigenetic regulation
  • HIRA is not only critical for HBB expression but is also required for activation of the erythropoietic regulators KLF1 and GATA binding protein 1 (GATA1)
  • KLF1 plays a role in facilitating and/or stabilizing GATA1 and TAL1 occupancy in the erythroid genes, contributing to the generation of active chromatin structure such as histone acetylation and chromatin looping
  • GATA2 counteracts the erythroid-specific transcription factor GATA1, to modulate the proliferation and differentiation of hematopoietic cells
