GATA binding protein 1

This gene encodes a protein which belongs to the GATA family of transcription factors. The protein plays an important role in erythroid development by regulating the switch of fetal hemoglobin to adult hemoglobin. Mutations in this gene have been associated with X-linked dyserythropoietic anemia and thrombocytopenia. [provided by RefSeq, Jul 2008] (from NCBI)

Novel players in β-thalassemia dyserythropoiesis and new therapeutic strategies.
Courtois et al., Paris, France. In Curr Opin Hematol, Feb 2016
Blocking GDF11 alleviates anemia in a mouse model of β-thalassemia and also in humans, most likely by promoting cells of 'good' erythroblastic lineage containing an α-/non-α-globin chain ratio of close to 1. Maturation arrest at the polychromatophilic stage (step 3) is associated with the depletion of GATA binding protein 1 (GATA-1) from the nucleus, which results from cytoplasmic sequestration of heat shock protein 70 (HSP70) by α-globin chains.

A Child With Dyserythropoietic Anemia and Megakaryocyte Dysplasia Due to a Novel 5'UTR GATA1s Splice Mutation.
Nalepa et al., Indianapolis, United States. In Pediatr Blood Cancer, Jan 2016
We show that (i) this constellation of hematopoietic abnormalities was due to a germline mutation within the 5' untranslated region (5'UTR) of globin transcription factor 1 (GATA1); (ii) the mutation impaired a 5'UTR GATA1 splicing site, with promoted production of the shortened GATA1 isoform lacking the N-terminus; and (iii) expression of the GATA1 N-terminus is restricted to erythroblasts and megakaryocytes in normal marrow, consistent with the patient's abnormal erythropoiesis and megakaryopoiesis.
Acute myeloid leukemia in children and adolescents: identification of new molecular targets brings promise of new therapies.
Meshinchi et al., Wilmington, United States. In Hematology Am Soc Hematol Educ Program, Jan 2016
A mutation in GATA1, common in AML of Down syndrome (ML-DS), renders cells more susceptible to cytarabine and anthracyclines, thus permitting targeted dose reductions to preserve high survival rates while reducing toxicity.
Erythropoiesis in vertebrates: from ontogeny to clinical relevance.
Fock et al., São Paulo, Brazil. In Front Biosci (elite Ed), Dec 2015
Several transcription factors and cytokines, such as GATA-1, GATA-2, FOG-1 and erythropoietin (EPO), constitute an elaborated molecular network that regulates erythropoiesis as they are involved in the differentiation and maturation of RBCs.
The biology of pediatric acute megakaryoblastic leukemia.
Downing et al., Memphis, United States. In Blood, Sep 2015
AMKL in children with Down syndrome (DS) is characterized by a founding GATA1 mutation that cooperates with trisomy 21, followed by the acquisition of additional somatic mutations.
Direct Induction of Hemogenic Endothelium and Blood by Overexpression of Transcription Factors in Human Pluripotent Stem Cells.
Slukvin et al., Madison, United States. In J Vis Exp, 2014
The combination of ETV2 and GATA1 or GATA2 TFs is used to induce HE with pan-myeloid potential, while a combination of GATA2 and TAL1 transcription factors allows for the production of HE with erythroid and megakaryocytic potential.
GATA family transcriptional factors: emerging suspects in hematologic disorders.

HSP70 sequestration by free α-globin promotes ineffective erythropoiesis in β-thalassaemia.
Courtois et al., Paris, France. In Nature, 2014
Although erythroid transcription factor GATA-1, the master transcriptional factor of erythropoiesis, is a caspase-3 target, it is not cleaved during erythroid differentiation.

Sankaran et al., Boston, United States. In Nat Med, 2014
Here, we identify mutations in GATA1, encoding the critical hematopoietic transcription factor GATA-binding protein-1, that reduce levels of full-length GATA1 protein and cause DBA in rare instances.

The landscape of somatic mutations in Down syndrome-related myeloid disorders.

Pathogenesis of these Down syndrome-related myeloid disorders is poorly understood, except for GATA1 mutations found in most cases.
A multiply redundant genetic switch 'locks in' the transcriptional signature of regulatory T cells.
Benoist et al., Boston, United States. In Nat Immunol, 2012
Enforced expression of Helios or Xbp1 elicited distinct signatures, but Eos, IRF4, Satb1, Lef1 and GATA-1 elicited exactly the same outcome, acting in synergy with Foxp3 to activate expression of most of the T(reg) cell signature, including key transcription factors, and enhancing occupancy by Foxp3 at its genomic targets.
GATA-1 utilizes Ikaros and polycomb repressive complex 2 to suppress Hes1 and to promote erythropoiesis.
Milot et al., Montréal, Canada. In Mol Cell Biol, 2012
results describe a mechanism whereby GATA-1 utilizes Ikaros and Polycomb repressive complex 2 to promote Hes1 repression as an important step in erythroid cell differentiation
Tissue-specific mitotic bookmarking by hematopoietic transcription factor GATA1.
Blobel et al., Philadelphia, United States. In Cell, 2012
Mitosis-specific destruction of GATA1 delays reactivation selectively of genes that retain GATA1 during mitosis; studies suggest a requirement of mitotic "bookmarking" by GATA1 for the faithful propagation of cell-type-specific transcription programs through cell division.

N- and C-terminal transactivation domains of GATA1 protein coordinate hematopoietic program.
Shimizu et al., Sendai, Japan. In J Biol Chem, 2012
GATA1 has two independent transactivation domains, N-TAD and C-TAD. Both N-TAD and C-TAD retain redundant as well as specific activities for proper hematopoiesis in vivo.
[GATA1-mutation associated leukemia in children with trisomy 21 mosaic].
Kolenova et al., Hannover, Germany. In Klin Padiatr, 2012
GATA1s associated leukemia has to be excluded in all young children with AMKL (<5 years old) to prevent overtreatment. Treatment with reduced intensity seems sufficient in children trisomy 21 mosaic and ML-DS.
