CREB-Binding protein acetylates hematopoietic transcription factor GATA-1 at functionally important sites.
The transcription factor GATA-1 is a key regulator of erythroid-cell differentiation and survival. We have previously shown that the transcriptional cofactor CREB-binding protein (CBP) binds to the zinc finger domain of GATA-1, markedly stimulates the transcriptional activity of GATA-1, and is required for erythroid differentiation. Here we report that CBP, but not p/CAF, acetylates GATA-1 at t...
متن کاملGATA-1 binding sites mapped in the beta-globin locus by using mammalian chIp-chip analysis.
The expression of the beta-like globin genes is intricately regulated by a series of both general and tissue-restricted transcription factors. The hemapoietic lineage-specific transcription factor GATA-1 is important for erythroid differentiation and has been implicated in regulating the expression of the erythroid-specific genes including the genes of the beta-globin locus. In the human erythr...
متن کاملGlobin gene activation during haemopoiesis is driven by protein complexes nucleated by GATA-1 and GATA-2.
How does an emerging transcriptional programme regulate individual genes as stem cells undergo lineage commitment, differentiation and maturation? To answer this, we have analysed the dynamic protein/DNA interactions across 130 kb of chromatin containing the mouse alpha-globin cluster in cells representing all stages of differentiation from stem cells to mature erythroblasts. The alpha-gene clu...
متن کاملDeterminants of GATA-1 Binding to DNA
Mammalian GATA transcription factors are expressed in various tissues in a temporally regulated manner. The prototypic member, GATA-1, is required for normal erythroid, megakaryocytic, and mast cell development. This family of DNA-binding proteins recognizes a consensus (A/T)GATA(A/G) motif and possesses homologous DNA binding domains consisting of two zinc fingers. The C-terminal finger of GAT...
متن کاملGATA-binding protein 1 is a novel transcription regulator of peroxiredoxin 5 in human breast cancer cells.
Peroxiredoxin 5 (Prx5) is a member of a family consisting of six antioxidant enzymes. Prx5 is ubiquitously expressed in various tissues including mitochondria and peroxisomes, implying that Prx5 functions as a regulator of the cellular oxidation state. Prx5 plays a critical role in protecting cells from oxidative stress by inhibiting the accumulat...
