該基因是髓系/淋巴系或混合系白血病（MLL）家族的成員，編碼核蛋白，具有AT-Hook DNA結合域、DHHC型鋅指、六個PhD型鋅指、一個集合域、一個后集合域和一個環狀鋅指。該蛋白是ASC-2/NCOA6復合物（ASCOM）的成員，具有組蛋白甲基化活性，參與轉錄協同激活。
This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a nuclear protein with an AT hook DNA-binding domain, a DHHC-type zinc finger, six PHD-type zinc fingers, a SET domain, a post-SET domain and a RING-type zinc finger. This protein is a member of the ASC-2/NCOA6 complex (ASCOM), which possesses histone methylation activity and is involved in transcriptional coactivation.
