Klf1 erythropoiesis
WebKrüpple-like factor 1 (KLF1, formerly known as EKLF) is a critical regulator of erythroid specific gene transcription [45]. It contains three zinc fingers and binds to the CACCC box. ChIP-sequencing analysis in erythroid cells revealed that KLF1 occupies a large number of genes expressed in erythroid cells. WebSep 29, 2024 · Krüppel-like factor 1 (KLF1) plays a crucial role in erythropoiesis. In-depth studies conducted on mice and humans have highlighted its importance in erythroid lineage commitment, terminal erythropoiesis progression and the switching of globin genes from γ to β. The role of KLF1 in haemoglobin switching is exerted by the direct activation of …

WebAs for GATA1, the first evidence for an essential role in erythropoiesis came from the observation that KLF1 knockout mice die in utero around E15 due to fatal anemia (Nuez et al., 1995; Perkins et al., 1995). Given that KLF1 is an important activator of β-globin, lethality was first attributed to β-thalassemia.
