Gene Information

human ... GFI1(2672)

General description

Gfi-1 is a zinc finger repressor that inhibits the proliferation and conserves functional integrity of hematopoietic stem cells. Human GFI1 mutations have been linked to neutropenia.
Rabbit Anti-GFI1 (AB1) antibody recognizes human, mouse, rat, and canine GFI1.

Immunogen

Synthetic peptide directed towards the N terminal region of human GFI1

Application

Rabbit Anti-GFI1 (AB2) antibody can be used for western blot applications at a concentration of 1μg/ml.

Biochem/physiol Actions

GFI1 may be a transcription factor involved in regulating the expression of genes active in the S phase during cell cycle progression in T-cells. GFI1 may be involved in tumor progression. Defects in GFI1 are a cause of autosomal dominant severe congenital neutropenia (SCN) and dominant nonimmune chronic idiopathic neutropenia of adults (NI-CINA) This gene encodes a nuclear zinc finger protein that functions as a transcriptional repressor. This protein plays a role in diverse developmental contexts, including hematopoiesis and oncogenesis. It functions as part of a complex along with other cofactors to control histone modifications that lead to silencing of the target gene promoters. Mutations in this gene cause autosomal dominant severe congenital neutropenia, and also dominant nonimmune chronic idiopathic neutropenia of adults, which are heterogeneous hematopoietic disorders that cause predispositions to leukemias and infections. Multiple alternatively spliced variants, encoding the same protein, have been identified for this gene.

Sequence

Haematopoietic stem cells (HSCs) sustain blood production throughout life. HSCs are capable of extensive proliferative expansion, as a single HSC may reconstitute lethally irradiated hosts. In steady-state, HSCs remain largely quiescent and self-renew at a constant low rate, forestalling their

Mice lacking the transcriptional repressor oncoprotein Gfi1 are unexpectedly neutropenic. We therefore screened GFI1 as a candidate for association with neutropenia in affected individuals without mutations in ELA2 (encoding neutrophil elastase), the most common cause of severe congenital neutropenia (SCN;
