Function
[GATA1_MOUSE] Transcriptional activator which probably serves as a general switch factor for erythroid development. It binds to DNA sites with the consensus sequence [AT]GATA[AG] within regulatory regions of globin genes and of other genes expressed in erythroid cells.[1] [2] [3] [4] [5] [USH_DROME] Transcription regulator that modulates expression mediated by transcription factors of the GATA family such as pnr and srp. Represses transcription of proneural achaete-scute complex (AS-C), which is usually activated by pnr. Involved in cardiogenesis, blood, and eye development. During hematopoiesis, it is required to restrict the number of crystal cells, probably via its interaction with the isoform SrpNC of srp. Negatively regulates expression of sr. Probably acts by interacting with the GATA-type zinc finger of proteins such as pnr and srp, possibly antagonizing the interaction between the GATA-type zinc finger and some cofactor.[6] [7] [8] [9] [10] [11]

Publication Abstract from PubMed
GATA-1 and friend of GATA (FOG) are zinc-finger transcription factors that physically interact to play essential roles in erythroid and megakaryocytic development. Several naturally occurring mutations in the GATA-1 gene that alter the FOG-binding domain have been reported. The mutations are associated with familial anemias and thrombocytopenias of differing severity. To elucidate the molecular basis for the GATA-1/FOG interaction, we have determined the three-dimensional structure of a complex comprising the interaction domains of these proteins. The structure reveals how zinc fingers can act as protein recognition motifs. Details of the architecture of the contact domains and their physical properties provide a molecular explanation for how the GATA-1 mutations contribute to distinct but related genetic diseases.
