basic FUNCTION
| red cell-specific transcription factor |
|
activating the beta globin synthesis in fetal liver and adult bone marrow |
|
directs different modes of tissue-specific transcriptional activation depending on the architecture of its target core promoter |
|
hematopoietic-specific transcription factor that is critical for the activation of subset of erythroid genes |
|
essential transcription factor for beta-type globin gene switching, and specifically activates transcription of the adult beta-globin gene promoter |
|
recruited to the gamma-globin gene promoter as a co-activator and is required for gamma-globin gene induction by short-chain fatty acid derivatives |
|
master regulator of adult beta-globin gene expression, and is also implicated in erythroid processes other than beta-globin gene regulation, such as cell maturation and cell membrane integrity |
|
restricts megakaryocytic differentiation to the benefit of erythrocytic differentiation and suggest that this might be at least partially mediated by the inhibition of FLI1 recruitment to megakaryocytic and FLI1 gene promoters |
|
likely in coordination with other transcription factors, directly contributes to the complex set of events that occur at the final erythroid cell divisions and accentuates terminal differentiation directly by activation of CDK inhibitors such as CDKN1A |
|
erythroid transcription factor, that plays a critical role in the expression of globin genes, but also in the expression of a wide spectrum of genes potentially essential for erythropoiesis |
|
potentially controls globin gene switching by directly activating beta-globin and indirectly repressing gamma-globin gene expression |
|
regulates definitive erythropoiesis of red blood cells by facilitating transcription through high affinity binding to CACCC elements within its erythroid specific target genes including those encoding erythrocyte membrane skeleton (EMS) proteins ( |
|
plays an important role in erythroid development by stimulating beta-globin gene expression |
|
plays essential roles in embryonic and adult erythropoiesis |
|
KLF1 and KLF2 positively regulate the embryonic and fetal beta-globin genes through direct promoter binding |
|
distinct yet overlapping mechanistic roles for KLF1 and KLF2 in embryonic red blood cells |
|
erythroid-specific transcription factor required for the transcription of genes that regulate erythropoiesis |
|
KLF1, KLF2, and MYC control a regulatory network essential for embryonic erythropoiesis |
|
important role for the KLF1-BCL11A axis in erythroid maturation and developmental regulation of globin expression |
|
acts as a direct activator of genes that encode repressors of gamma-globin gene expression, and is a regulator of many components of the cell cycle machinery |
|
crucial zinc finger transcription factor, is expressed in the erythro-myeloid progenitors (EMPs), and plays an extrinsic role in erythroid maturation by being expressed in the supportive macrophage of the erythroblastic island and regulating relevant genes important for island integrity within these cells |
|
in erythroid cells, expression of KLF1 precedes PGF, and its enforced expression in human erythroid progenitor cells induces PGF mRNA |
|
KLF1 and KLF2 coordinately regulate embryonic erythroid precursor maturation through the regulation of multiple homeostasis-associated genes |
|
is an erythroid specific transcription factor that binds to regulatory regions of erythroid genes |
|
regulates BCL11A, a known repressor of adult gamma-globin expression |
|
role of KLF1 in gamma-globin regulation in fetal erythroblasts is complex, with both positive and negative facets |
|
transcription factors such as KLF1, along with epigenetic modifiers, play crucial roles in establishing the proper onset and progression of terminal differentiation events in erythropoiesis |
|
essential transcription factor that is required for the proper maturation of the erythroid cells |
