  • FunctionTranscription factor regulating the expression of genes active during S-phase of the cell cycle in hematopoietic cells. Represses ELA2 transcription.
  • Involvement in diseaseDefects in GFI1 are a cause of neutropenia severe congenital autosomal dominant type 2 (SCN2) [MIM:613107]. SCN2 is a disorder of hematopoiesis characterized by a maturation arrest of granulopoiesis at the level of promyelocytes with peripheral blood absolute neutrophil counts below 0.5 x 10(9)/l and early onset of severe bacterial infections.
    Defects in GFI1 are a cause of dominant nonimmune chronic idiopathic neutropenia of adults (NI-CINA) [MIM:607847]. NI-CINA is a relatively mild form of neutropenia diagnosed in adults, but predisposing to leukemia in a subset of patients.
  • Sequence similaritiesContains 6 C2H2-type zinc fingers.
  • DomainThe Gly/Ala-rich region may indicate that Gfi-1 is a repressor of its target genes.

    Performed under reducing conditions.

    Predicted band size : 45 kDa
    Observed band size : 49 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 36 kDa (possible cleavage fragment,cross reactivity).

    ab21061 detects a band of ~49kDa which is similar to the expected size of GFI1 (45kDa). This band is competed away by incubation with the immunizing peptide. A smaller band (~36kDa) is seen that may correspond to a crossreacting peptide or to a degradation product, as it is also competed away by addition of the immunizing peptide.
