Epigenetic Interplay Between Histone H3k9me2 And Jil-1 Mediated Histone H3s10ph, Chao Wang
Graduate Theses and Dissertations
In Drosophila, JIL-1 Kinase specifically localizes to euchromatic interband regions of polytene chromosomes and is responsible for histone H3S10 phosphorylation at interphase. Previous genetic interaction assays have demonstrated that the JIL-1 protein can counterbalance the effect of the major heterochromatin components Su(var)3-7 on position-effect variegation (PEV). In this study, we show that the haplo-enhancer effect of JIL-1 has the ability to counterbalance the haplo-suppressor effect of two other major heterochromatin components, Su(var)3-9 and Su(var)2-5, on position-effect variegation, providing evidence that a finely tuned balance between the levels of JIL-1 and the major heterochromatin components ...
