Human Polyclonal GFI1B Primary Antibody for WB - ABIN1881370
Rödel, Wagner, Zörnig, Niessing, Möröy: The human homologue (GFI1B) of the chicken GFI gene maps to chromosome 9q34.13-A locus frequently altered in hematopoietic diseases. in Genomics 1999

High GFI1B expression is associated with small-cell lung cancer.
Results demonstrate that alpha-delta platelet storage pool deficiency is associated with either a heterozygous mutation in GFI1B (de novo or familial) abrogating the binding of the zinc fingers with the promoter of its target genes, or by hypomorphic biallelic mutations leading to autosomal recessive inheritance.
study demonstrates the significance of Gfi1b regulated Kindlin3-Talin1 expression in driving megakaryocytic differentiation and highlights the contribution of cytoskeletal agents in the developmental progression of these platelet progenitors
Role for Alternative GFI1B Splice Variants in Human Hematopoiesis
SPI1 (show SPI1 Antibodies)-GFI1B transcriptional network is an important regulatory axis in acute myeloid leukemia (show BCL11A Antibodies) as well as in the development of erythroid versus myelomonocytic cell fate
Gfi1b functions as a transcriptional repressor by recruiting histone-modifying enzymes to promoters and enhancers of target genes. Mutations are associated with certain bleeding disorders. Review.
a mutation in GFI1B causes a platelet disorder; GFI1B has a role a critical regulator of platelet shape, number, and function
results, supported by evidence from mouse models, identify GFI1 (show ZNF163 Antibodies) and GFI1B as prominent medulloblastoma oncogenes and implicate 'enhancer hijacking' as an efficient mechanism driving oncogene (show RAB1A Antibodies) activation in a childhood cancer
TAL1 (show TAL1 Antibodies) is involved in regulating H3K27me3 variations in collaboration with GFI1B
Silencing of both BCR-ABL (show ABL1 Antibodies) siRNA and GFI1B siRNA is associated with an additive antileukemic effect against K562 cells.
These findings suggest that Gfi1.1 plays a critical role in regulating the balance of embryonic erythroid and myeloid lineage determination, and is also required for the differentiation of lymphocytes and granulocytes during zebrafish embryogenesis.
We conclude that Gfi1b controls major functions of megakaryocytes such as integrin-dependent cytoskeleton organization, spreading and migration through the regulation of PAK activity whereas the proplatelet formation defect in GFI1B-deficient megakaryocytes is due, at least partially, to an insufficient alpha-tubulin (show TUBA4A Antibodies) content.
these results identify Rgs18 (show RGS18 Antibodies) as a new and crucial effector of Gfi1b that regulates downstream signaling and gene expression programs to orchestrate erythro-megakaryocytic lineage choices.
Gfi1b is a regulator of embryonic globin expression and embryonic and adult erythroid maturation.
Gfi1 (show ZNF163 Antibodies) and gfi1b repress rag transcription in plasmacytoid dendritic cells in vitro.
GFI1B, EVI5 (show EVI5 Antibodies), MYB (show MYB Antibodies) are additional mouse genes that cooperate with the human BCL6 (show BCL6 Antibodies) gene to promote the development of lymphomas.
There is direct yet differential regulation of meis1 (show MEIS1 Antibodies) transcription by Gfi1b in distinct hematopoietic lineages.
GFI1 (show ZNF163 Antibodies) and GFI1B are able to trigger, in the absence of RUNX1 (show RUNX1 Antibodies), the down-regulation of endothelial markers and the formation of round cells, a morphologic change characteristic of endothelial to hematopoietic transition.
Gfi family members are essential for normal B cell development and play an important role in modulating expression of the V(D)J recombinase (show RAG1 Antibodies).
The transcription factor Gfi1b defines the brush cell lineage and its progenitors, and with Hes1 and Atoh1 (show ATOH1 Antibodies) forms a fate-determining Notch (show NOTCH1 Antibodies) signaling driven ternary switch in the developing intestinal epithelium.
Essential transcriptional regulator necessary for development and differentiation of erythroid and megakaryocytic lineages. Alters histone methylation by recruiting histone methyltransferase to target genes promoters. Plays a role in heterochromatin formation.
