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. [provided by RefSeq, Sep 2011]

A study in head and neck squamous cell carcinoma (HNSCC) demonstrated that targeting the CD276 remodels tumor heterogeneity by reducing epithelial-to-mesenchymal transition and promotes CD8+ T cell infiltration to kill cancer stem cells [Li et al. DOI:10.1038/s41368-021-00146-0]. A study in mice demonstrated that the immune checkpoint molecules CD200 and LGALS9 were identified as crucial immune molecules associated with septic cardiomyopathy via differential expression analysis [Zhao et al. DOI:10.2147/JIR.S486763].
