一般描述
Monoclonal Anti-Growth Factor Independence-1 (GFI1) (mouse IgG1 isotype) is derived from the hybridoma 2.5D.17 produced by the fusion of mouse myeloma cells (SP2 cells) and splenocytes from BALB/c mice immunized with rat GFI1. Growth Factor Independence 1 (GFI1) is a zinc-finger transcriptional repressor, that is located on human chromosome 1p22. Gfi1 is highly expressed in thymus while Gfi1B is the predominant factor expressed in spleen, and both are expressed in bone marrow. It has a repression domain named SNAG at the N-terminal.† The protein also has a zinc finger DNA binding domain that is homologous to the domain in Gfi1B. Both bind to same consensus DNA sequence
特异性
The antibody epitope resides within the GFI1 SNAG transcriptional-repression domain (amino acids 7-26).
免疫原
rat growth factor independence-1 (GFI1).
应用
Monoclonal Anti-Growth Factor Independence-1 (GFI1) antibody may be used in:
- immunoblotting
- immunohistochemistry
- EMSA (electrophoretic mobility shift analysis)
生化/生理作用
Growth factor independence-1 (Gfi1) plays a key role in hematopoiesis along with Gfi1B proteins. Cytokines that regulate innate immunity induce Gfi1 expression. Deficiency of this protein causes thymic and peripherial T lymphopenia and severe abnormalities in pre-T-cell development in mice. Mutations in this gene cause defects in T lymphocyte function and development in humans. Gfi1 autoregulates its expression in T lymphocytes.

T cell differentiation in the thymus is dependent upon signaling through the TCR and is characterized by the resulting changes in expression patterns of CD4 and CD8 surface coreceptor molecules. Although recent studies have characterized the effects of proximal TCR

The zinc finger protein growth factor independent-1 (Gfi1) is a transcriptional repressor that is critically required for normal granulocytic differentiation. GFI1 loss-of-function mutations are found in some patients with severe congenital neutropenia (SCN). The SCN-associated GFI1-mutant proteins act as dominant

Growth factor independence-1 (GFI1) and GFI1B are closely related, yet differentially expressed transcriptional repressors with nearly identical DNA binding domains. GFI1 is upregulated in the earliest thymocyte precursors, while GFI1B expression is restricted to T lymphopoiesis stages coincident with activation.
