We found that corepressor Ski binds to TRIM27, and that TRIM27 contributes to deubiquitination via forming a complex with USP7. It was found that TRIM27 enters into the nucleus in response to poly(I-C) stimulation, suggesting that Ski ubiquitination may be regulated by TRIM27 in response to specific signaling.In knockout mice of transcriptional adaptor Shn-2, T cell differentiation in thymus is blocked. It was found that Shn-2 is modified by O-GlcNAc at several sites which modulates nuclear entry of Shn-2. It was demonstrated that Shn-2 is localized on the T-cell receptor beta gene locus, and modulated allelic exclusion.

我们发现辅阻遏物 Ski 与 TRIM27 结合，并且 TRIM27 通过与 USP7 形成复合物而有助于去泛素化。研究发现TRIM27响应poly(I-C)刺激而进入细胞核，这表明TRIM27可能响应特定信号而调节Ski泛素化。 在转录接头Shn-2的敲除小鼠中，胸腺中的T细胞分化被阻断。发现Shn-2在多个位点被O-GlcNAc修饰，从而调节Shn-2进入核。结果表明，Shn-2 定位于 T 细胞受体 β 基因位点，并调节等位基因排除。
