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.

A study in mice demonstrated that the KLF1 was upregulated in common in splenocytes at day 7 post-injury following both burn and trauma-hemorrhage, where it was categorized as a gene expression marker within the antiapoptosis pathway [Lederer et al. DOI:10.1152/physiolgenomics.00086.2007].
