These genes expressed specifically in erythroid tissue and differentially expressed in a precise temporal order during development. It has been shown that interaction of erythroid specific trans-acting factors with cis-acting elements may play an important role in regulation of globin gene expression. Here we mainly focus on introducing three erythroid specific factors of KLF family (EKLF, FKL and FKLF-2), including their structure, fuction and interaction with other trans-acting factors. Previous studies have revealed that they may be critical in the developmental regulation of globin gene expression. Key words: erythoid KLF factors; CACCC box; proteins interaction *Corresponding author, E-mail: qianlab@sunm.ac.cn |
