CD276（CD276 molecule），癌症关联基因，基因ID：80381，该基因编码的蛋白属于免疫球蛋白超家族，参与调节t细胞介导的免疫应答。研究表明，尽管该基因的转录本在正常组织和实体瘤中广泛表达，但该蛋白只在肿瘤组织中优先表达。此外，我们还观察到该转录本的3’utr含有mir29 microrna的靶位点，并且该蛋白的表达与mir29水平呈负相关，这表明mir29对该基因产物的表达具有调节作用。另外，已经发现该基因编码不同亚型的剪接转录变体。[由RefSeq提供，2011年9月]The protein encoded by this gene belongs to the immunoglobulin superfamily， and thought to participate in the regulation of T-cell-mediated immune response. Studies show that while the transcript of this gene is ubiquitously expressed in normal tissues and solid tumors， the protein is preferentially expressed only in tumor tissues. Additionally， it was observed that the 3' UTR of this transcript contains a target site for miR29 microRNA， and there is an inverse correlation between the expression of this protein and miR29 levels， suggesting regulation of expression of this gene product by miR29. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.。
