Abstract
Recent studies have demonstrated that histone methylation can be dynamically regulated through active demethylation. However, no demethylase specific to histone H3 trimethyl-Lys4 (H3K4me3) has been identified. Here we report that the Drosophila melanogaster protein 'little imaginal discs' (Lid), a JmjC domain-containing trithorax group protein, can demethylate H3K4me3. Consistent with its genetic classification, Lid positively regulates Hox gene expression in S2 cells.
