别名 Activation B7-2 antigen、B-lymphocyte antigen B7-2、B7-2 + [11] |
简介 Receptor involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4 (PubMed:12196291). 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 IgG(1) produced. Upon CD40 engagement, activates NF-kappa-B signaling pathway via phospholipase C and protein kinase C activation (By similarity).
(Microbial infection) Acts as a receptor for adenovirus subgroup B.
Interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation. |
