該基因位于X染色體上，是編碼四肽重復序列（TPR）蛋白的Y連鎖基因的相應位點。該基因的編碼蛋白包含一個JMJC結構域，并催化三/二甲基化組蛋白H3的去甲基化。已發現該基因的多個選擇性剪接轉錄變體。
This gene is located on the X chromosome and is the corresponding locus to a Y-linked gene which encodes a tetratricopeptide repeat (TPR) protein. The encoded protein of this gene contains a JmjC-domain and catalyzes the demethylation of tri/dimethylated histone H3. Multiple alternatively spliced transcript variants have been found for this gene.
