[Effect of Ikaros in B Cell Acute Lymphoblastic Leukemia]

The Ikaros - a DNA-binding zinc finger protein, acting as a regulator of chromatin remodeling and gene transcription, is crucial for regulating the development and function of the immune system and acting as a master regulator of hematopoietic differentiation. Function-loss mutations of IKZF1, gene encoding Ikaros are frequent in B cell acute lymphoblastic leukemia (B-ALL) and are associated with a poor prognosis. This review briefly summarizes the available data regarding the structure and function of Ikaros, the role of Ikaros as a tumor suppressor in B-ALL, and its regulation mechanism.
