CRYSTAL STRUCTURE OF THE CTLA-4/B7-2 COMPLEXCRYSTAL STRUCTURE OF THE CTLA-4/B7-2 COMPLEX

Structural highlights

1i85 is a 4 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 3.2Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

CD86_HUMAN 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.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
