The molecular events and transcriptional mechanisms that underlie erythropoiesis are of great interest to biologists and hematologists since disorders of erythrocytes are common and remain relatively poorly understood. Kruppel-like factor 1 (KLF1) is a critical transcription factor for erythropoiesis in mice and man. Recently the use of chromatin immunoprecipitation (ChIP) coupled to next-generation DNA sequencing (ChIP-seq) has led to an updated understanding of how KLF1 functions in vivo. The full extent of KLF1 target genes have provided new insights into erythropoiesis, and have established that KLF1 controls almost all aspects of erythroid cell development and maturation.
