Protein Structure

UniProt Annotation

Function

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.

Subcellular Localization

Cell membrane; Single-pass type I membrane protein.

Disease Associations

Tissue Specificity

Expressed by activated B-lymphocytes and monocytes.
