Demethylation of trimethylated histone H3 Lys4 in vivo by JARID1 JmjC proteins.
Seward D.J., Cubberley G., Kim S., Schonewald M., Zhang L., Tripet B., Bentley D.L.
Histone H3 Lys4 trimethylation (H3-K4me3) is a conserved mark of actively transcribed chromatin. Using a conditional mutant of the yeast H3-K4 methyltransferase, Set1p, we demonstrate rapid turnover of H3-K4me3 and H3-K4me2 in vivo and show this process requires Yjr119Cp, of the JARID1 family of J ... >> More

Using a conditional mutant of the yeast H3-K4 methyltransferase, Set1p, we demonstrate rapid turnover of H3-K4me3 and H3-K4me2 in vivo and show this process requires Yjr119Cp, of the JARID1 family of JmjC proteins. Ectopic overexpression of mouse Jarid1B, a Yjr119Cp homolog, greatly diminished H3-K4me3 and H3-K4me2 in HeLa cells, suggesting these proteins function as K4 demethylases in vivo. << Less

Changes in histone methylation status regulate chromatin structure and DNA-dependent processes such as transcription. Recent studies indicate that, analogous to other histone modifications, histone methylation is reversible. Retinoblastoma binding protein 2 (RBP2), a nuclear protein implicated in the regulation of transcription and differentiation by the retinoblastoma tumor suppressor protein, contains a JmjC domain recently defined as a histone demethylase signature motif. Here we report that RBP2 is a demethylase that specifically catalyzes demethylation on H3K4, whose methylation is normally associated with transcriptionally active genes. RBP2-/-mouse cells displayed enhanced transcription of certain cytokine genes, which, in the case of SDF1, was associated with increased H3K4 trimethylation. Furthermore, RBP2 specifically demethylated H3K4 in biochemical and cell-based assays. These studies provide mechanistic insights into transcriptional regulation by RBP2 and provide the first example of a mammalian enzyme capable of erasing trimethylated H3K4. << Less

Histone methylation regulates chromatin structure and transcription. The recently identified histone demethylase lysine-specific demethylase 1 (LSD1) is chemically restricted to demethylation of only mono- and di-but not trimethylated histone H3 lysine 4 (H3K4me3). We show that the X-linked mental retardation (XLMR) gene SMCX (JARID1C), which encodes a JmjC-domain protein, reversed H3K4me3 to di- and mono-but not unmethylated products. Other SMCX family members, including SMCY, RBP2, and PLU-1, also demethylated H3K4me3. SMCX bound H3K9me3 via its N-terminal PHD (plant homeodomain) finger, which may help coordinate H3K4 demethylation and H3K9 methylation in transcriptional repression. Significantly, several XLMR-patient point mutations reduced SMCX demethylase activity and binding to H3K9me3 peptides, respectively. Importantly, studies in zebrafish and primary mammalian neurons demonstrated a role for SMCX in neuronal survival and dendritic development and a link to the demethylase activity. Our findings thus identify a family of H3K4me3 demethylases and uncover a critical link between histone modifications and XLMR. << Less

Methylation of histones has been regarded as a stable modification defining the epigenetic program of the cell, which regulates chromatin structure and transcription. However, the recent discovery of histone demethylases has challenged the stable nature of histone methylation. Here we demonstrate that the JARID1 proteins RBP2, PLU1, and SMCX are histone demethylases specific for di- and trimethylated histone 3 lysine 4 (H3K4). Consistent with a role for the JARID1 Drosophila homolog Lid in regulating expression of homeotic genes during development, we show that RBP2 is displaced from Hox genes during embryonic stem (ES) cell differentiation correlating with an increase of their H3K4me3 levels and expression. Furthermore, we show that mutation or RNAi depletion of the C. elegans JARID1 homolog rbr-2 leads to increased levels of H3K4me3 during larval development and defects in vulva formation. Taken together, these results suggest that H3K4me3/me2 demethylation regulated by the JARID1 family plays an important role during development. << Less
