TRIP-Br2 是一种细胞周期调节因子，能与DP-1 特异性结合，参与转录因子E2F-1/DP-1 介导的转录增殖活动，维持基因组 稳定性。在能量代谢方面，TRIP-Br2 作用于启动子E2F-1，抑制脂解作用，降低机体能量代谢率。TRIP-Br2 过度表达可激活E2F-1/ DP-1 介导的细胞周期调控，导致基因组稳定性下降，促进肿瘤的发生。同时，高水平的 TRIP-Br2 可诱导棕色脂肪细胞释放炎症因子 和急性期反应蛋白，产生炎症反应和急性相位反应。该文对 TRIP-Br2 的自身分子结构及其在增殖、代谢、炎症等过程中的生物学作 用进行综述。

TRIP-Br2 (transcriptional regulator interacting with the PHD zinc finger and/or the bromodomain 2) is a kind of cell cycle regulator, which can specifically bind to transcription factor DP-1 (DRTF-1-polypeptide-1) and participate in E2F-1 (E2 factor-1)/DP-1-mediated transcriptional proliferative activities and maintain genome stability. As for energy metabolism, overexpression of TRIP-Br2 activates E2F-1/DP-1-mediated cell cycle regulation, leading to decreased genomic stability and promoting oncogenesis. High levels of TRIP-Br2 can induce brown adipocytes to release inflammatory factors and acute phase response proteins, producing inflammatory responses and acute phase responses. This paper summarizes the molecular structure of TRIPBr2 and its biological role in proliferation, metabolism, and inflammation.
