MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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. [provided by RefSeq, Oct 2009]
PHENOTYPE: Nullizygous mice exhibit fatal anemia due to impaired hemopoiesis in fetal liver. Homozygotes for an ENU-induced allele die at E10-11 with severely impaired hemopoiesis while surviving heterozygotes show hemolytic anemia with reduced RBC counts, hematocrit and hemoglobin, and altered RBC morphology.
