该基因编码的蛋白质通过与几个核受体（包括雌激素、维甲酸和维生素D3受体）的激活功能2（AF2）区域相互作用介导转录控制蛋白质定位于核体，被认为与染色质和异染色质相关因子有关。该蛋白是TRIM家族的一员修剪基序包括三个锌结合域-一个环，一个B盒类型1和一个B盒类型2-和一个螺旋线圈区域已经描述了编码不同亚型的两个选择性剪接转录变体。
The protein encoded by this gene mediates transcriptional control by interaction with the activation function 2 (AF2) region of several nuclear receptors, including the estrogen, retinoic acid, and vitamin D3 receptors. The protein localizes to nuclear bodies and is thought to associate with chromatin and heterochromatin-associated factors. The protein is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains - a RING, a B-box type 1 and a B-box type 2 - and a coiled-coil region. Two alternatively spliced transcript variants encoding different isoforms have been described for this gene.
