CD86

CD86 (CD86 Molecule) is a Protein Coding gene. Diseases associated with CD86 include Gallbladder Squamous Cell Carcinoma and Myocarditis. Among its related pathways are Cytokine Signaling in Immune system and Th2 Differentiation Pathway. Gene Ontology (GO) annotations related to this gene include receptor binding and coreceptor activity. An important paralog of this gene is CD80.

CD86 Molecule

CD86 Molecule; CD86 Antigen (CD28 Antigen Ligand 2, B7-2 Antigen); CTLA-4 Counter-Receptor B7.2; CD28LG2; FUN-1; BU63; B70; B-Lymphocyte Activation Antigen B7-2;

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 (PubMed:7527824).
Also involved in the regulation of B cells function, plays a role in regulating the level of IgG1 produced. Upon CD40 engagement, activates NF-kappa-B signaling pathway via phospholipase C and protein kinase C activation (By similarity).
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.
