Loss-Offunction Afleles Of The Jil-1 Kinase Are Strong Suppressors Of Position Effect Variegation Of The W(M4) Allele In Drosophila

In this article we show that hypomorphic loss-of-function alleles of the JIL-1 histone H3S10 kinase are strong suppressors of position effect variegation (PEV) of the w(m4) allele and that lack of JIL-1 activity can counteract the effect of the dominant enhancer E(var)2-1 on PEV.
