Abstract excerpt
It has recently been demonstrated that activity of the essential JIL-1 histone H3S10 kinase is a major regulator of chromatin structure and that it functions to maintain euchromatic domains while counteracting heterochromatization and gene silencing. In the absence of JIL-1 kinase activity, the major heterochromatin markers histone H3K9me2 and HP1 spread in tandem to ectopic locations on the chromosome arms. In...
