Abstract: Up to the mark Two papers in this issue identify enzymes capable of demethylating a trimethyl group from the Lys 9 residue of histone H3 — a 'mark' required for the establishment of heterochromatin and previously considered stable. Cloos et al. show that GASC1, a member of the JMJD2 enzyme family, can disrupt heterochromatin structure when overexpressed and may contribute to tumour development. Klose et al. show that overexpression of JHDM3A, also a JMJD2-type enzyme, disrupts heterochromatin structure. It may function in euchromatin to regulate transcription.
