GeneID: 17



Names

Common Name: KLF1 Type: Gene
Chromosome: 19 (NC_000019.10) Locus: NG_013087.1 (KLF1)
HUGO Symbol: KLF1 Full Name: Kruppel-Like Factor 1
Exons: 3 Introns: 2

Description:
The encoded protein is a transcription regulator of erythrocyte development that probably serves as a general switch factor during erythropoiesis. KLF1 contains 3 zinc fingers homologous to those found in the Kruppel family of transcription factors. It is a dual regulator of fetal-to-adult globin switching; it binds to a CCACACCCT sequence found in the beta-globin gene promoter, thus activating adult globin gene expression, and also to the BCL11A gene promoter, thus activating BCL11A transcription which in turn mediates repression of fetal globin genes. This dual activity ensures that, in most adults, fetal haemoglobin levels are low. In addition, KLF1 interacts with CBP/p300 and BRG1, which is a component of the chromatin remodeling complex SWI/SNF. Moreover, KLF1 is able to activate CD44 and AQP1 promoters, and heterozygous loss-of-function mutations in this gene result in the dominant In(Lu) blood phenotype.

Synonyms: EKLF , erythroid Kruppel-like factor
