Abstract: Heterochromatin protein 1 (HP1), a gene silencing protein, localizes to centric heterochromatin through an interaction with methylated K9 of histone H3, a modification generated by the histone methyl transferase SU(VAR)3-9. On Drosophila polytene chromosomes, HP1 also localizes to 200 sites scattered throughout euchromatin. To address the role of HP1 in euchromatic gene regulation, mRNAs from wild-type and Su(var)2-5 mutants lacking HP1 were compared. Genes residing within a 550-kb genomic region enriched in …
