Recruitment of ikaros to pericentromeric heterochromatin is regulated by phosphorylation.

Ikaros encodes a zinc finger protein that is involved in heritable gene silencing. In hematopoietic cells, Ikaros localizes to pericentromeric heterochromatin (PC-HC) where it recruits its target genes, resulting in their activation or repression via chromatin remodeling. The function of Ikaros is controlled by post-translational modifications. CK2 kinase… CONTINUE READING
