Ikaros is a transcription factor that is encoded by the IKZF genes of the Ikaros family zinc finger group. Zinc finger is a small structural motif of protein that allows protein binding to DNA or RNA molecule that is characterized by the coordination of one or more zinc ions (Zn2+) in order to stabilize the fold. Ikaros displays crucial functions in the hematopoietic system and is a known regulator of immune cells development, mainly in early B cells, CD4+ T cells. Its dysfunction has been linked to the development of chronic lymphocytic leukemia. In particular, Ikaros has been found in recent years to be a major tumor suppressor involved in human B-cell acute lymphoblastic leukemia and that it also has a part in the differentiation and function of individual T helper cells. Ikaros also has a role during the later stages of B cell development during VDJ recombination in switch class of the antibody isotypes and expression of the B cell receptor. SNPs located near the 3' region of IKZF1 in humans have been linked to susceptibility to childhood acute lymphoblastic leukemia (ALL) as well as type 1 diabetes. The two effects appear to be in opposite directions, with the allele marking susceptibility to ALL protecting from T1D and vice versa.
