Function
Jumonji domain-containing protein 2A (Jmjd2a) catalyzes the demethylation of trimethylated histone at lysine residues 9 and 36 producing the dimethylated form. Jmjd2a domains contain: N-terminal, catalytic core (residues 1-350), 2 TUDOR domains (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.
