该基因位于X染色体上，是编码四肽重复序列（TPR）蛋白的Y连锁基因的相应位点。该基因的编码蛋白包含一个JMJC结构域，并催化三/二甲基化组蛋白H3的去甲基化。已发现该基因的多个选择性剪接转录变体。
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.
