Biological function summary
GATA1 regulates gene expression and is essential for erythroid and megakaryocyte differentiation. GATA1 belongs to a family of GATA transcription factors and can form regulatory complexes with other proteins such as FOG1 (Friend of GATA1) and TAL1. These complexes facilitate the binding of GATA1 to DNA enhancing its transcriptional activity on target gene sets necessary for blood cell maturation and function.
Pathways
GATA1 participates in the erythropoiesis and megakaryopoiesis pathways. It directly regulates several genes and coordinates signals with factors like GATA2 and RUNX1 which are other key proteins involved in these pathways. Through these interactions GATA1 ensures the correct development of red blood cells and platelets maintaining hematopoietic homeostasis in the organism.

General info
Function
Transcriptional activator or repressor which serves as a general switch factor for erythroid development (PubMed : 35030251). It binds to DNA sites with the consensus sequence 5'-[AT]GATA[AG]-3' within regulatory regions of globin genes and of other genes expressed in erythroid cells. Activates the transcription of genes involved in erythroid differentiation of K562 erythroleukemia cells, including HBB, HBG1/2, ALAS2 and HMBS (PubMed : 24245781).
Post-translational modifications
Highly phosphorylated on serine residues. Phosphorylation on Ser-310 is enhanced on erythroid differentiation. Phosphorylation on Ser-142 promotes sumoylation on Lys-137 (By similarity).. Sumoylation on Lys-137 is enhanced by phosphorylation on Ser-142 and by interaction with PIAS4. Sumoylation with SUMO1 has no effect on transcriptional activity (By similarity).. Acetylated at 2 conserved lysine-rich motifs by CREBBP in vitro. Acetylation does not affect DNA-binding in vitro but is essential to induce erythroid differentiation and for binding chromatin in vivo (By similarity). Acetylated on Lys-233, Lys-245 Lys-246 by EP300.
