Human Kruppel-Like Factor 1 (erythroid) (KLF1) interaction partners

  1. Activation of KLF1 at day 10 of the differentiation process when hematopoietic progenitor cells were present, enhanced erythroid commitment and differentiation.

  2. Hereditary persistence of fetal hemoglobin (show HBB Proteins) in two patients with KLF1 haploinsufficiency due to 19p13.2-p13.12/13 deletion

  3. NF-E2, TAL1 and KLF1, all activators play a primary role in HSs formation in the LCR

  4. Introduction of the British HPFH mutation into the fetal globin promoter in a human cell model causes elevated fetal globin expression. The British HPFH mutation creates a de novo binding site both in vitro and in vivo for the potent erythroid activator KLF1.

  5. A hypothesis on possible liaisons between mutations in the gene encoding EKLF and resistance to pathogens is presented.

  6. study reports a novel KLF1 mutation codon 211 A-->G (c.632 A>G) in a family with beta-hemoglobinopathy showing a considerable increase in the HbF level, thus supporting the role of KLF1 in hemoglobin switching

  7. seven new alleles in the KLF1 gene, which are presumed to act dominantly to silence LU expression, were identified

  8. The prevalence of the In(Lu) phenotype in the Japanese population was 0.02%, and we identified 13 known and 21 novel KLF1 alleles. The KLF1 mutations cause the reduced expression of the P1 antigen.

  9. Our study highlighted two novel promoter KLF1 and 3'-region C/EBPalpha motifs in the phenylalanine hydroxylase (PAH) gene which decrease transcription in vitro and, thus, could be considered as PAH expression modifiers.

  10. a broad range of hitherto unrelated human red cell disorders are caused by variants in KLF1, a master regulator of erythropoiesis, which were previously considered to be extremely rare causes of human genetic disease [review]

Mouse (Murine) Kruppel-Like Factor 1 (erythroid) (KLF1) interaction partners

  1. KLF1 and KLF3 (show KLF3 Proteins) bind common as well as unique sites within the erythroid cell genome.

  2. The semi-dominant neonatal anemia (Nan) mutation in the EKLF/KLF1 transcription factor leads to ectopic expression of proteins that are not normally expressed in the red blood cell, leading to systemic effects that exacerbate the intrinsic anemia in the adult and alter correct development in the early embryo.

  3. Point mutations in the erythroid transcription factor, Klf1: one mutation, D11 generates a stop codon in the zinc finger domain and a homozygous null phenotype; another mutation, D45, generates an amino acid transversion (H350R) within a linker between zinc fingers two and three.

  4. Data indicate that PIAS3 (protein inhibitor of activated STAT3 (show PIAS3 Proteins)) interaction modulates EKLF (erythroid Kruppel-like factor) activity in a promoter-dependent and SUMO-independent manner.

  5. Hemin-induced expression of PlGF (show PGF Proteins) is abolished in EKLF-deficient erythroid cells but rescued by conditional expression of EKLF.

  6. HIRA (show HIRA Proteins) is not only critical for beta-globin (show HBB Proteins) expression but is also required for activation of the erythropoietic regulators EKLF and GATA binding protein 1 (GATA1).

  7. KLF1 and KLF2 (show KLF2 Proteins) coordinately regulate embryonic erythroid precursor maturation through the regulation of multiple homeostasis-associated genes.

  8. EKLF mRNA has exon skipping only in primary tissues. The splice variant is at a low level in embryonic and adult erythroid cells, and in terminal differentiation. The truncated protein partially encodes a non-erythroid Kruppel-like factor AA sequence.

  9. Dok2 is able to control Klf1 expression by transcriptional regulation through directly binding to its promoter region.

  10. EKLF plays a coordinating role between two different cell types whose interaction provides the optimal environment to generate a mature red blood cell

KLF1 Protein Profile

Protein Summary

This gene encodes a hematopoietic-specific transcription factor that induces high-level expression of adult beta-globin and other erythroid genes. The zinc-finger protein binds to the DNA sequence CCACACCCT found in the beta hemoglobin promoter. Heterozygous loss-of-function mutations in this gene result in the dominant In(Lu) blood phenotype.
