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 lymphohistiocytoid mesothelioma and autoimmune disease of central nervous system. Among its related pathways are Signaling by GPCR and Immune System. GO annotations related to this gene include receptor binding and coreceptor activity. An important paralog of this gene is CD80.
UniProtKB/Swiss-Prot 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.
