BACKGROUND The Jumonji (Jmj) gene was identified by a mouse gene trap approach and has essential roles in the development of multiple tissues. The Jmj protein has a DNA binding domain, ARID, and two conserved Jmj domains (JmjN and JmjC).
Several proteins in the Jumonji family are involved in transcriptional repression and/or chromatin regulation.1 Recently, human members of the family have been shown to be a histone demethylases, and the JmjC domain is essential for demethylase activity.2
Jumonji domain containing 1B (JMJD1B, also known as KDM3B/JHDM2B) contains a highly-conserved C-terminus, which includes a zinc finger with the unique spacing Cys-X2-Cys-X7-His-X2-Cys-X2-Cys-X4-Cys-X2-Cys and a JmjC domain. JMJD1B has been shown to be a histone demethylase responsible for demethylating mono methyl histone H3 at K9.3 Methylation of H3-K4 and H3-K9 is linked to transcriptional activation and repression, respectively. JMJD1B plays an important role in chromatin regulation and gene expression, and controls development through various signaling pathways. It may also be a candidate for tumor suppressors.
