Abstract

Methylation of histone H3 lysine 4 is linked to active transcription and can be removed by LSD1 or the JmjC domain-containing proteins by amino-oxidation or hydroxylation, respectively. Here we describe that its deamination can be catalyzed by lysyl oxidase-like 2 protein (LOXL2), presenting an unconventional chemical mechanism for H3K4 modification. Infrared spectroscopy and mass spectrometry analyses demonstrated that recombinant LOXL2 specifically deaminates trimethylated H3K4. Moreover, by regulating H3K4me3 deamination, LOXL2 activity is linked with the transcriptional control of the CDH1 gene. These results reveal the existence of further H3 modification as well as a novel mechanism for H3K4me3 demethylation.
