This domain is found in Ribosomal oxygenase 1 from humans (RIOX1) and similar proteins from animals. RIOX1 catalyse histidine- hydroxylation in ribosomal protein rpL28. The protein shows a JmjC domain followed by an helical dimerization domain and a C-terminal winged-helix (WH)-domain (this entry) [1,2].	Domain

This entry includes proteins with a JmjC domain that belong to the cupin superfamily, including Bifunctional lysine-specific demethylase and histidyl-hydroxylase NO66 [1], Ribosomal oxygenase 1/2 [2,3], and 50S ribosomal protein L16 3-hydroxylase from Escherichia coli [4,5]. Proteins are bifunctional, acting as histone lysine demethylases and ribosomal histidine hydroxylases.	Domain
