This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.[provided by RefSeq, May 2011]
GeneCards Summary for CD86 Gene
CD86 (CD86 Molecule) is a Protein Coding gene. Diseases associated with CD86 include Acute Myocarditis and Myocarditis. Among its related pathways are Th1 Differentiation Pathway and Downstream signaling events of B Cell Receptor (BCR). Gene Ontology (GO) annotations related to this gene include signaling receptor binding and coreceptor activity. An important paralog of this gene is CD80.
UniProtKB/Swiss-Prot Summary for CD86 Gene
Receptor involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4. May play a critical role in the early events of T-cell activation and costimulation of naive T-cells, such as deciding between immunity and anergy that is made by T-cells within 24 hours after activation. Isoform 2 interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation.
(Microbial infection) Acts as a receptor for adenovirus subgroup B.
