General annotation (Comments)

Function

Histone demethylase that specifically demethylates 'Lys-36' of histone H3, thereby playing a central role in histone code. Preferentially demethylates dimethylated H3 'Lys-36' residue while it has weak or no activity for mono- and tri-methylated H3 'Lys-36'. May also recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation. Required to maintain the heterochromatic state. Associates with centromeres and represses transcription of small non-coding RNAs that are encoded by the clusters of satellite repeats at the centromere. Required to sustain centromeric integrity and genomic stability, particularly during mitosis By similarity.

Catalytic activity

Protein N6,N(6)-dimethyl-L-lysine + 2-oxoglutarate + O2 = protein N(6)-methyl-L-lysine + succinate + formaldehyde + CO2.

Protein N(6)-methyl-L-lysine + 2-oxoglutarate + O2 = protein L-lysine + succinate + formaldehyde + CO2.

Cofactor

Binds 1 Fe2+ ion per subunit By similarity.

Subcellular location

Nucleus › nucleoplasm By similarity.

Domain

The JmjC domain mediates demethylation activity and is required for satellite silencing By similarity.

Sequence similarities

Belongs to the JHDM1 histone demethylase family.

Contains 1 CXXC-type zinc finger.

Contains 1 F-box domain.

Contains 1 JmjC domain.

Contains 3 LRR (leucine-rich) repeats.

Contains 1 PHD-type zinc finger.
