Jumonji domain-containing protein

spinqualitylabelsall models Structure of human Jumonji domain-containing protein 2a catalytic domain complex with oxalylglycine, Fe+2 ion (orange), Zn+2 ion (grey) and histone H3 peptide (aqua) with trimethyllysine (magenta) (PDB code 2p5b).

Jmjd2a domains contain: N-terminal, catalytic core (residues 1-350), 2 TUDOR domains which recognize dimethylated Arg (residues 895-1011) , 2 PHD-type zinc fingers and C-terminal domain. Jmjd2a is Fe+2 and α-ketoglutarate dependent. Methylation of histones in the chromatin is involved in regulation of gene activity, chromatin structure and epigenetic memory. Jumonji domain-containing protein 2b (Jmjd2b) or KDM4B and Jumonji domain-containing protein 2d (Jmjd2d) or KDM4D catalyze the demethylation of trimethylated histone H3 at lysine residues 9 producing the dimethylated form. Jumonji domain-containing protein 3 (Jmjd3) or KDM6B and Jumonji domain-containing protein 2d (Jmjd2d) or KDM4D catalyze the demethylation of trimethylated histone H3 at lysine residues 27 producing the dimethylated form. Jumonji domain-containing protein 5 (Jmjd5) or KDM8 and Jumonji domain-containing protein 6 (Jmjd6) function as histone demethylase and as a protein hydroxylase. Disease Jmjd6 serves as a receptor allowing the foot-and-mouth virus to infect cells. Structural highlights Jmjd2a uses 9 residues for interaction with the methylated peptide and 4 residues are involved with binding to the peptide's trimethyllysine moiety. An O2 molecules are recruited into the catalytic center. Water molecules shown as red spheres.
