Functioni
Plays a critical role in induction and maintenance of immune tolerance to self (PubMed:11015443, PubMed:28813417, PubMed:28813410). As a ligand for the inhibitory receptor PDCD1/PD-1, modulates the activation threshold of T-cells and limits T-cell effector response (PubMed:11015443, PubMed:28813417, PubMed:28813410). Through a yet unknown activating receptor, may costimulate T-cell subsets that predominantly produce interleukin-10 (IL10) (PubMed:10581077).4 Publications
The PDCD1-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and escape destruction by the immune system, thereby facilitating tumor survival (PubMed:28813417, PubMed:28813410). The interaction with PDCD1/PD-1 inhibits cytotoxic T lymphocytes (CTLs) effector function (By similarity). The blockage of the PDCD1-mediated pathway results in the reversal of the exhausted T-cell phenotype and the normalization of the anti-tumor response, providing a rationale for cancer immunotherapy (By similarity).By similarity2 Publications

Involvement in diseasei
Truncation of the 3'-untranslated (3'-UTR) region of CD274 transcripts leads to elevated expression of CD274 in multiple cancers including T-cell leukemia, diffuse large B-cell lymphoma and stomach adenocarcinoma (PubMed:27281199). Disruption of 3'-UTR region is caused by structural variants that stabilize CD274 transcripts, leading to overexpression (PubMed:27281199). Increased expression in tumors promotes immune evasion and tumor cell growth by allowing malignant cells to escape destruction by the immune system (PubMed:27281199).1 Publication
