a ubiquitous protein demethylase that specifically demethylates Lys-9 of histone H3, thereby playing a central role in histone code. Demethylation of Lys residue generates formaldehyde and succinate. May have tumor suppressor activity. Three alternatively spliced isoforms have been reported. Note: This description may include information from UniProtKB.
Protein type: Demethylase; EC 1.14.11.-; Oxidoreductase
