这个基因编码的蛋白质是三部分基序（trim）家族的成员。装饰图案包括三个锌结合域、一个环、一个B盒类型1和一个B盒类型2，以及一个卷曲的线圈区域。这种磷蛋白定位于核体，在那里作为转录因子和肿瘤抑制因子发挥作用。其表达与细胞周期相关，并调节p53对致癌信号的反应。该基因常与急性早幼粒细胞白血病（APL）相关的维甲酸受体α基因易位有关。这种基因的广泛选择性剪接导致蛋白质的中心和C端区域的几种变异；所有的变异编码相同的N端。另外，还发现了编码不同亚型的剪接转录变体。
The protein encoded by this gene 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. This phosphoprotein localizes to nuclear bodies where it functions as a transcription factor and tumor suppressor. Its expression is cell-cycle related and it regulates the p53 response to oncogenic signals. The gene is often involved in the translocation with the retinoic acid receptor alpha gene associated with acute promyelocytic leukemia (APL). Extensive alternative splicing of this gene results in several variations of the protein's central and C-terminal regions; all variants encode the same N-terminus. Alternatively spliced transcript variants encoding different isoforms have been identified.
